Heterochromia iridium is a condition in which people have eyes of different colours. For example a blue eye and a brown eye (like Alexander the Great, David Bowie or Kate Bosworth). Or two different shades of blue (like Kiefer Sutherland). It is also known as complete hetereochromia. This is...

Personally, I think the title of the episode is misleading. I think the title of this thread would be a more accurate description of this insitome podcast. They talk about how some genetic influences on phenotype may have led to some legends and myths. It's pretty interesting, and I'd suggest...

The quality of gene sequencing has improved so much and its price has fallen so far that a start-up now says it can offer the service for free. Nebula Genomics aims to sequence a customer’s entire genome, according to the company’s chief scientific officer Dennis Grishin. In contrast, current...

How to see the problem of genetically modified food? Is genetically modified food safe? What are the harms to humans? Which countries currently import the most GM crops? img: credit

Hi I have just found this study: https://www.researchgate.net/figure/Distribution-of-the-Yamnaya-genetic-component-in-the-populations-of-Europe-data-taken_fig2_318751121 which shows a different map for the Yamnaya admixture than the one included in this site... interestingly, in the map here...

Here is a long article published by the researcher himself in The Conversation about the presumed origins of cystic fibrosis, the most common genetic disease among people of European descent. Discovering the ancient origin of cystic fibrosis, the most common genetic disease in Caucasians...

The number of genes encoding proteins in the human genome keeps shrinking as the mapping of the proteome nears completion. Medical News Today: One in five human genes are not 'real' "The initial results of the Human Genome Project predicted that there are 40,000 genes that can encode proteins...

That is big news. That protein could be the main culprit behind autism. Knowing how it works and how to fix imbalances could be the key to curing (at least some types of) autism. Hundreds of autism genes found to be triggered by a single key protein "Despite some exciting recent advances in...

Can someone give me the rundown/history on these subclades and explain their prevalence in Southern Italy/Sicily? I just ran a Morley prediction report via my 23andMe test, and this was the most likely prediction. I also ordered the Y37 test from FTDNA and ancestry.com as well. I had done...

Found this on Phys.org: Sweeping gene survey reveals new facets of evolution "Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge? And who would have thought to...

Evolution may be responsible for a range of complex traits, including height and waist-to-hip ratio, and diseases such as schizophrenia, research from The University of Queensland shows. The findings improve understanding of how natural selection shapes human populations, and could lead to...

If this is true it is potentially a Nobel-winning discovery. BBC News: 'Memory transplant' achieved in snails "A team successfully transplanted memories by transferring a form of genetic information called RNA from one snail into another. The snails were trained to develop a defensive...

The study on Lombard DNA by Amorim et al. (2018) was already discussed a few months ago as part of a preliminary paper, but did not yet include the Y-DNA and mtDNA tables. This is still a pre-print, but at least we can see what haplogroups the Lombards carried. The admixtures for each sample...

We found out last year that the Emperors of Japan probably belonged to haplogroup D1b1a2 based on the tests of various descendants. Another presumed descendant of the imperial family tested at Family Tree DNA and also belonged to that haplogroup, and more precisely to the D-Z1504 subclade. A...

Johane Derite posted a list of different phylogenetic trees of IE languages proposed by various linguists in another thread. I thought it would be an ideal opportunity for me to post my proposed phylogenetic tree, which I have not only based on linguistic evidence, but also on archaeological and...

I just read an interesting post on how 23andMe reported Y haplogroup analysis in the report of a person who always knew that she is a biological woman. Any thoughts about this? I was thinking about genetic mosaicism and androgen insensitivity syndrome.

I have updated and expanded the phylogenetic tree of haplogroup E-V13. I changed the layout to show when each clade developed in time so as to get a better idea of when the regional expansions happened. Many branches of the tree are still missing. There are few Greek, Italian, French and...

In 2017 I started a thread encouraging users to share their 23andMe Ancestry Composition to get a better idea of what each admixture corresponds to. This resulted in the making of distribution maps for each European admixture. I would now like to do the same for people who have uploaded their...
