Ordered Two New SNPS Test for Goldfoot
I was just told that we could order SNPS for $29 each so I ordered 2 of them just now; the L245 and the L272 that are advised for our Q1b branch on the tree. (I've since read that L272 is rare, so we may not reflect this SNP. )
This is getting very technical, but up to this point I had found out that our place on the tree was a Q1b branch with the SNP's of P36.2+M378+. These two new ones may or may not apply to us, so I have to find out. They're the ones we should take. What if it shows nothing? What will it show?
I read in my dna book that there are SNPs on every chromosome and there are 10 million of them in nuclear DNA. They account for 90% of the genetic variation in humans. The Y SNPs used for genetic genealogy are not the only ones on the Y-chromosome, either. They just are the ones used by population geneticists and genetic genealogists. A SNP is also known as a polymorphism. it is possible that the same alteration is in less than 1% of another population and then is considered to be a mutation. What's being tested are SNPs used in genetic genealogy. They give information in finding the origins and migration patterns of indigenous peoples. but is only an indicator of the development of present populations. What must be done is to correlate theories of population development based on SNPs with archeological and anthropological evidence SNPs are markers with 2 values. They have mutated only once in human history. Each SNP can be traced to a single common ancestor where it first appeared.
The earliest SNPs can be traced to a Y chromosome Adam who lived between 60,000 and 90,000 years ago and a Mitochondrial Eve who lived about 150,000 years ago. These are the only ones who have survived to the present day, but we know there had been others who didn't. .
What's interesting to me is that haplogroup Q is found most frequently in Eastern Europe and Scandinavia, having originated in Central Asia and migrated through the Altai/Baikai region of northern Eurasia into the Americas. This is referring to the native Americans who are a Q3, as I remember. Q1b's were found mostly in Eastern Europe. I don't know what my mother's Swedish grandfather would have been, but it would be something if he were also a Q. Now I"m excited about getting the results of this test.
From wiki: According to Behar et al. 5% of Ashkenazi males belong to haplogroup Q.[20] This has subsequently been found to be entirely the Q-M378 subclade and may be restricted to Q-L245.
5/3/2011: From http://en.wikipedia.org/wiki/Haplogroup_Q_(Y-DNA) The Q-M378 subclade and specifically its Q-L245 subbranch is speculated to be the branch to which Q-M242 men in Jewish Diaspora populations belong.[20][32] Although published articles have not tested for M378 in Jewish populations, genetic genealogists from the Ashkenazi, Mizrachi, and Sephardi Jewish populations have tested positive for both M378 and L245.
