23andMe finally unveiled a Neanderthal Ancestry estimation feature. I'm at ~2.4 percent. What I'm curious about is the fact that out of the 45 "friends and family" who are surveyed, only two are at 3 percent.
One of my them is my sibling who I found seems to have the Neandertal copy of a dystrophin variant!
I have hypothesized that this may be the reason for his relatively robust build (he looks a lot like me, except kind of Neandertaloid). Also of curiosity, I'm the least Neandertal in my family, including my parents!
