Analysis of the Degree of Consanguinity across the Qatari Subgroups as Compared to the HGDP Bedouin Sample

Quantile-quantile plot comparing the Wright's inbreeding coefficient (f) as calculated with PLINK for each individual in each Qatari subgroup with the coefficients of each individual in the HGDP Bedouin sample. The plot indicates that the Qatar1 subgroup contains individuals with higher levels of consanguinity than individuals in the Bedouin sample. The Qatar2 subgroup contains individuals with a lesser degree of consanguinity (the trend of points below the diagonal) compared to individuals in the Bedouin sample, although there are two outlying individuals with unusually high consanguinity. Finally, the Qatar3 subgroup appears to be far less consanguineous than the Bedouin sample.
