This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

Because of course I'm going to find something about dogs...

At-home genome sequencing tests were all the rage this holiday season, but for those of us with mixed-breed dogs, or mutts, we've seen this trend for quite some time. For several years now companies like Wisdom Panel have been marketing kits to dog adopters dying to know what breed(s) their pets were (or weren't).

The merits of that are debatable, but a recent Slate article describes using this owner reported-data to find an allele responsible for producing blue eyes in huskies (and some other dogs) as one of the first successes in terms of crowdsourcing genotypic and phenotypic data.

See the original study in pre-print here -- it has broader implications for the study of human disease, as more than 70 single-mutation diseases in canines have analogues in the human genome.
