  1. All values are given as averages over the 37 control loci.
  2. Group 1 and Group 2 are the two groups inferred using Instruct on sequence data obtained on control loci: Group 2 is the Spain-Morocco group and Group1 the eastern part of the sample (Figure 1)
  3. &: per site estimates are reported here,
  4. #: Z standardization of Fay and Wu's H.
  5. N/A: not applicable.
  6. The value Hudson's ρ reported here is the average of ρ estimates per analysed site.
