Yesterday the first batch of results from 23andMe’s v3 chip came online. Instead of 550,000 SNPs you get ~1 million. The difference is pretty clear when you look at the raw SNPs. Under Account → Browse Raw Data, I can enter LCT, and this is what I see:
I’m line #2. A sibling is line #1. Looking at this sort of stuff makes it really likely I’ll upgrade. My main rationale for not upgrading is that there’s diminishing marginal returns for ancestry related stuff. Speaking of ancestry, let’s compare my sibling’s ancestry painting to my own.
In a bit of a surprise, while I’m 43% “Asian,” my sibling is 40% “Asian.” This is somewhat reflected in global similarity.

I was curious if the differences were v3 vs. v2 chip, so I compared two individuals of Northern European ancestry:
Northern Europe v2
Northern Europe v3

There’s less of a consistent difference here. So I really don’t know what to think.
