Zack's Genome Public

Posted by on July 27, 2011 2 comments

I have released my 23andme version 3 genome into the public domain.

I challenge y'all to find anything interesting about my chromosome 9 (which is 93% homozygous).ragrani.ru

Also, I got my parents' 23andme results last night.

Harappa Participants Haplogroups

Posted by on July 22, 2011 35 comments

All the ancestry analysis here has been based on the autosomal genome (i.e., the SNPs on chromosomes 1-22) and not on the sex chromosomes X and Y or the mitochondrial DNA. The reason is basically that the autosome provides information about your overall ancestry.

Since the Y chromosome is inherited only from father to son, it is useful for finding out about your paternal line. Similarly, mitochondrial DNA is inherited from mother to child, so that's good for information on the maternal line. Note however that the paternal and maternal lines are not the sum total of your ancestry. In fact, it is quite possible to have very different mtDNA or Y-DNA ancestry compared to your whole genome.

Anyway, many people are interested in paternal (Y-DNA) haplogroups and maternal (mtDNA) haplogroups. AV requested information on the haplogroups of Harappa Project participants and SB created a spreadsheet where project participants can enter their paternal and maternal haplogroups. I am also pulling that information into my Harappa Participants Ethnicity spreadsheet.

If you tested with 23andme, here are the links to their maternal and paternal haplogroup pages.

Now go ahead and enter your information in the haplogroups spreadsheet.

You might also want to take a look at the Harappa Participants Map.

UPDATE: Please be considerate of others' privacy. Only disclose someone else's information (haplogroups, location, or anything else) if you have explicit permission to do so. Thanks!

Admixture (Ref3 K=11) HRP0141-HRP0150

Here are the admixture results using Reference 3 for Harappa participants HRP0141 to HRP0150.

You can see the participant results in a spreadsheet as well as their ethnic breakdowns and the reference population results.

Here's our bar chart and table. Remember you can click on the legend or the table headers to sort.

If the above interactive charts are not working, here's a static bar graph.

150 and 100

The total number of participants has gotten to 150. The Harappa Ancestry Project has been active for a little less than 6 months.sports74.ru

Of these, depending on how you count, we are at about 100 unrelated South Asians.infolio-rg.ru

Sorry for my absence from the comment section and the slow pace of posting. There's a lot of backlog of work and home errands that accumulated during my vacation.

Back

I got back yesterday. Due to jetlag and things that accumulated during my absence, it'll take me a few days to get back to regular posting here.ir-leasing.ru

I got about 12 data submissions during my vacation. I'll send everyone their Harappa IDs by tomorrow. If you haven't received an ID from me by Thursday morning, drop me an email to remind me.rpk-tramplin.ru

I have 2 batches of ten to process for Admixture results. I hope to post those by the end of the week but can't make any promises.

If you sent me an email in the last month that required a response, I will try to reply soon. If you haven't heard from me by July 11, please remind me.

Thanks, Razib, for your guest blogging.

Brahui are something old, not new

Posted by on July 3, 2011 15 comments

From Wikipedia:

The ethnonym "Brahui" is a very old term and a purely Dravidian one. The fact that other Dravidian languages only exist further south in India has led to several specualations about the orgins of the Brahui. There are three hypotheses regarding the Brahui that have been proposed by academics. One theory is that the Brahui as a relic population of Dravidians, surrounded by speakers of Indo-Iranian languages, remaining from a time when Dravidian was more widespread. Another theory is that they migrated to Baluchistan from inner India during the early Muslim period of the 13th or 14th centuries. More established theory says the Brahui migrated to Balochistan from central India after 1000 CE. The absence of any older Iranian (Avestan) influence in Brahui supports this hypothesis. The main Iranian contributor to Brahui vocabulary is a western Iranian language like Kurdish.

A lot of ADMIXTURE plots I've seen are more consistent with the first (indigenous) than the latter two (exogenous) models. Here's a result for K = 9 with ~90,000 markers:
