Цитата:
Which data did you use?
The dataset we analyzed here consists of 1,490 individuals sampled from 95 world-wide groups with 2-
46 individuals per group. For each individual, we had genotypes at 474,491 genetic markers (Single-Nucleotide-Polymorphisms; SNPs) across all 22 non-sex chromosomes. These data included both new
samples and samples collated from multiple publicly available resources.
How have you defined a “group”?
There is a long-standing debate spanning several scientific fields about what constitutes a “group” or
“population”. For our analysis here, we define a “group” to be a set of individuals whom all have a
similar genetic make-up. This is initially based on labels given by researchers during the sampling
process (which are dependent on self-identification) but in some cases we refined groups to better
reflect genetic similarity using the fineSTRUCTURE algorithm (see below).
