dN/dS at ABS |
Historic balancing selection |
High dN/dS indicates positive selection at sites that recognize pathogens |
Reduced in species with non-functional duplicated loci; reduced in species with lower effective population sizeand stronger genetic drift |
dS-dN at non-ABS |
Purifying selection |
High dS–dN indicates greater rates of silent substitutions that preserve amino acid configurations at sites surrounding ABS |
Higher in species with duplicated loci to preserve allelic divergence; reduced in species with lower effective population size and stronger genetic drift |
Average nucleotide divergence (π) |
Genetic diversity |
Extent of variation between sequences |
Higher in species with duplicated loci; higher in species with larger effective population size |
Number of alleles |
Genetic diversity |
Number of unique sequences |
Higher in species with duplicated loci; higher in species with larger effective population size |
