Strain-specific Minor Allele Frequencies (MAF) at the G2:F1 and G2:F7 generations. Strain-specific MAF in the G2:F1 (A) generation depicts less variation than the G2:F7 (B) generation, with some spread of allele frequencies evident in the G2:F7 generation. Allele frequency distributions become asymmetrical for some strains. The distribution becomes right skewed for PWK/PhJ, indicating that more loss than gain has occurred, and left skewed for WSB/EiJ.
