Species genetic variation and number of subspecies/races/breeds/breeding populations/clusters etc.

A straightforward research idea: Compare the recognized count of subspecies (races/breeds/breeding populations/clusters etc.) with measures of genetic variation. The most obvious is the Fst but it's not an optimal metric.…

A partial test of DUF1220 for population differences in intelligence?

You might have heard the DUF1220 hypothesis, it goes something like this: DUF1220 is a copy number variant poorly tagged by arrays, and thus would not be captured well by…
