The Clan Colla 425 Null Project was launched on 22 June 2009.

The three Collas were three brothers in Ulster:  Colla Uais, Colla da Crioch, and Colla Menn .  The descendants of Colla Uais moved to the Scottish Highlands.

Descendants of the Collas are identified at three single nucleotide polymorphisms (SNPs): L21+, DF21+, and DNS425 null. The null DNA425 occurred in the early part of the first millennium.

There are many surnames in Clan Colla, including Carroll, Hughes, MacDougall, McDonald, McGuire, McKenna, McMahon .  See O’Hart, John. 1892. Irish pedigrees; or, The origin and stem of the Irish nation. Dublin: James Duffy and Co., available on Google Books.

There are 259 people in the project .  Of the new FTDNA Y-DNA markers (68-111), members of Clan Colla have a value of 9 for marker DNS 505.

The Family Tree DNA GAP (Group Administration Page) 2.0 was launched in November 2010 .  The Family Finder autosomal DNA test platform was changed from Affymetrix chips to Illumina chips in January 2011 .  Family Tree DNA has processed 2.33 PB (petabytes) of matching data for Family Finder.

The SNP (single nucleotide polymorphism) ordering tree was modified, making it easier to order SNPs .  New downstream SNPs were added and the Y-DNA test was expanded from 67 to 111 markers .  Family Tree DNA intends to release new SNPs more quickly.

Family Tree DNA acquired the DNA Heritage Y-DNA (Y chromosomal) database, but not the mtDNA (mitochondrial DNA) database because the two companies did not sequence the same region of mtDNA.

The myFTDNA 2.0 homepage will be released soon .  Project administrators will be able to try the myFTDNA before the project members .  The General Fund is easier to use, a new messaging system from FTDNA to customers has been added, and a new configurable profile for users has been added .  Privacy settings have been added to the profile .  There are specialized resources for each section of the myFTDNA page, Family Finder matches, new images, a link to the profile, and badges .  Y-DNA haplogroup matches have been expanded.

New features allow you to see matches just for a particular project .  A new power search feature has been added, allowing the user to combine the power of all three DNA types in a search .  Family Finder upgrades include new SNPs, fewer false positives, and the ability to upload data from 23andMe (v3 only).

Microalleles can be displayed on GAP charts .  Microalleles are displayed as decimals in three quarter steps: 0.1, 0.2, 0.3 (0.4 is the next higher number of repeats) .  Changes in palindromic markers are now treated as a single step mutation, rather than multiple step mutations, reflecting the number of events rather than the size of the events .  STR (short tandem repeat) values will adhere to NIST standards.

At the Seventh International Family Tree DNA Conference for Group Administrators, Michael Hammer, PhD presented a talk on “Neandertals in Our Midst: Just How Modern is Our Genome?”

What did Darwin have to say about human evolution?  He avoided the subject .  It was actually Thomas Henry Huxley who discussed evidence as to man’s place in nature.

If all species of the genus Homo (Homo erectus, Homo neanderthalensis, Homo sapiens, among others) are considered humans, did modern man replace older forms or was there gene flow among species that coexisted at one time?  Did archaic forms of humans leave behind DNA evidence?

An indirect method of inferring the past uses contemporary DNA, molecular dating, and single locus phylogeography .  From this type of evidence we know that, since there is greater genetic diversity in Africa, the root of the human evolutionary tree is among Africans .  In Newsweek magazine, on 11 January 1988, the press coined the term “Mitochondrial Eve.”

A direct method of inferring the past uses ancient DNA .  Using this approach, there is no evidence for a Neandertal contribution to mitochondrial DNA (mtDNA).

Analysis of the Y chromosome (Y-DNA) by indirect approaches shows greater African diversity, an African root, with a time to the most recent common ancestor (TMRCA) of about 130 KYA.

Analysis of the X chromosome (X-DNA) by indirect approaches shows a greater Asian diversity, an Asian root, with a TMRCA of about 2 MYA.

The DNA of three Neandertals has been analyzed .  The data from this analysis shows that there was a little interbreeding of Neandertals with Eurasians, but not with Africans.

Evidence shows that after humans left Africa, they bred with Neandertals and then that population interbred with the Denisovians in Melanesia .  There is Denisovian (from the Denisova cave in Siberia) DNA on chromosome 12, a greater Melanesian diversity, and a Melanesian root.

An innate immunity gene STAT2 introgressed (moved from one species to another) from the Neandertal and is positively selected in Melanesia .  Interbreeding of modern man with Neandertals led to an advantage.

Inferring the past using an indirect method involving contemporary DNA, molecular dating, and a computational approach shows that chromosomes 4, 18, and 13 entered African DNA relatively recently, providing evidence for interbreeding of modern man with a now extinct hominid form in Africa.

DNA evidence allows us to reject the theory of recent African replacement.

Bloggers who have discussed Neandertal DNA include John Hawkes.

At the Seventh International Family Tree DNA Conference for Group Administrators, Katherine Hope Borges and Alice Fairhurst led a meeting of the Family Tree DNA Chapter of ISOGG (International Society of Genetic Genealogy).

ISOGG was started in 2005 after the 2004 Family Tree DNA Conference for Group Administrators .  The ISOGG wiki has added the ability to create a book about anything.

There has been increased movement towards regulation of DTC (direct to consumer) DNA tests, especially medical tests.

In a 2011 survey of the ASHG (American Society of Human Genetics), 74% said that DTC tests should not be available for all purposes, 84% were in favor of DTC tests, but consumers should be aware of the limitations .  Regarding the availability of DTC ancestry tests, 60% were in favor, 20% were neutral, and 20% were against.

The ISOGG PAC (Political Action Committee) is not related to money.

California added genetic information to the list of information that people cannot be discriminated against .  The new law (SB559) becomes effective on 01 January 2012 .  This is stronger than GINA (Genetic Information Nondiscrimination Act of 2008) .  GINA failed several times before it was passed.

ISOGG wanted a clearing house to name Y-DNA subclades based on new SNPs (single nucleotide polymorphisms) .  ISOGG needs the help of members to identify new SNPs .  The majority of men in ISOGG are in haplogroup R .  ISOGG prepares a Y-DNA haplogroup map and updates it when new information is available .  This map is in harmony with the YCC (Y Chromosome Consortium), but it is not identical to the Family Tree DNA Y haplogroup map because the Family Tree DNA haplogroup map is updated less frequently than is the ISOGG haplogroup map.

The Armenian DNA Project is a large project with 570 members. Historically, Armenia covered a much larger area than it does today and includes several languages.

Armenian DNA exhibits extreme diversity. There are 14 y-DNA haplogroups and 80 distinct clades. Major Y-DNA haplogroups include R1b, J2, G, and J1. Armenians in the R1b haplogroup belong to the older root of R1b, not the Western European root. Armenians come from diverse but ancient origins tied by common language, religion (Christian), and customs.

Armenian mtDNA includes 13 major haplogroups and 70 distinct clades.

Armenians and Assyrians fall into the same Y-DNA and mtDNA haplogroups and Kurdish Jews have similar Y-DNA haplogroups as Armenian.  Iraqi Kurds have a slightly greater East Asian component than other groups in the area.

At the Seventh International Family Tree DNA Conference for Group Administrators,
David Pike, PhD presented a talk entitled “Phasing & Other Analysis of Family Finder Results”.

David Pike

David has written a number of utilities for processing unzipped autosomal DNA files from either Family Tree DNA or 23 and Me. The utilities may be found at http://www.math.mun.ca/~dapike/FF23utils/.

Phasing entails separating a child’s alleles inherited from the father from those inherited from the mother. It is one of the more informative used of DNA data and it enables the reconstruction of ancestral chromosomes.

Example:  At a particular locus, the mother’s DNA shows that she has an A and a T, the father’s DNA shows that he has a T and a T, and their child’s DNA shows that (s)he has an A and a T. The child must have inherited the A from the mother, since the father does not have an A at either allele. Therefore, the child must have inherited the T from the father.

If the child has runs of homozygosity (a sequence of bases that are the same in each of the two alleles) such as:

GAGAGCAC
GGGAGCAG

(where A = adenine, C = cytosine, G = guanine, and T = thymine) there may be evidence that the parents are related to each other.

In analyzing the DNA, one may find a discordance. Microdeletions and copy number variations may result in some SNPs having only one allele, in which case the allele is reported twice.

DNA results are reported with 99.99% accuracy. Still, this means that 1 in 10,000 SNPs are miscalled, resulting in genotyping errors.

One may discover actual mutations – de novo mutations in the child.

A child may have a longer match with a cousin than the parent does due to false matches that coincidentally match the cousin.

Phasing a child is straightforward when raw data files are available for the child and both parents. Runs of homozygosity (ROHs) and matching blocks of DNA between relatives can be used to partially phase DNA. One parent and several siblings can also be phased, as can siblings alone, although phasing works better with data from one or both parents. Results may be enhanced if one sibling has already been phased.

At the Seventh International Family Tree DNA Conference for Group Administrators, Bruce Walsh, PhD presented a talk entitled “Genetic Genealogy Q&A”. I was particularly interested in this talk because, while I know quite a bit about Y-DNA and mitochondrial DNA (mtDNA), I am relatively new to Family Finder, Family Tree DNA’s version of autosomal DNA analysis.

Two random people differ at 20 million out of 3 billion bases in their DNA. The differences include short tandem repeats (STRs) which have many alleles (forms) and high mutation rates) and single nucleotide polymorphisms (SNPs) which typically have two alleles and low mutation rates.

Of the 46 chromosomes and mtDNA in humans, 44 chromosomes comprise the 22 pairs of autosomes, the X chromosome, the Y chromosome, and the mt chromosome. The Y chromosome and the mt chromosome are passed from generation to generation intact.

Because the Y chromosome and mt chromosome do not undergo recombination, they are useful for tracing the strict paternal ancestry (father’s father’s father, etc.) and strict maternal ancestry (mother’s mother’s mother, etc.) of an individual, but are not useful for following any other ancestral lines (such as mother’s father’s mother or father’s mother’s father). For these lines of ancestry that are not strictly paternal or maternal, one must analyze the inheritance of the 22 pairs of autosomes.

While the Y chromosome and the mt chromosome are passed from generation to generation intact, the autosomes are recombined or shuffled from one generation to the next. Unfortunately, because of recombination, if two people share a common ancestor, the autosomal DNA shared by those two people is less and less the farther back their common ancestor.

If two people are separated from their most recent common ancestor (MRCA) by one generation, the probability that those two people share at least one intact autosome is 0.99999976 (almost certain). If two people are separated from their MRCA by two generations, the probability is 0.947. If they are separated by three generations, the probability drops to 0.502. Four generations apart, and the probability is 0.158. Six generations, and the probability is 0.01068729. Seven generations, and the probability is only 0.00268211.

Because of recombination, the autosomes usually don’t get passed on to the next generation intact. So, as the autosomes are recombined, blocks of DNA, rather than intact autosomes, are passed on from one generation to the next.

TMRCA – Average Size of Block
1 – 44.06 cM
2 – 19.15 cM
3 – 12.30 cM
4 – 9.07 cM
5 – 7.19 cM
6 – 5.95 cM
7 – 5.08 cM

TMRCA = time to the most recent common ancestor (generations).
cM = centimorgan, a measure of distance in DNA corresponding to a 1% chance of recombination, or approximately 1 million DNA base pairs in humans.

When analyzing autosomal DNA results, the total amount of shared DNA allows an estimate of close relationships (1-3 generations). For more distantly related individuals, the size of the largest block of shared DN is used to estimate relationships.

Common blocks of DNA may be analyzed to determine whether the block of DNA is inherited from the father or the mother. This process is called phasing. The Y chromosome is inherently phased because it is inherited from the father. The X chromosome in males is also inherently phased because it must have been inherited from the mother.
