Abstract

We have developed two pieces of Perl and Python codes to calculate the natural log of lambda, a quantity that expresses deviations from Hardy–Weinberg equilibrium, and R, a weighted correlation coefficient between alleles of locus pairs as a quantity that expresses linkage disequilibrium. These quantities can be used in an estimation approach as tools to facilitate the characterization and the comparison of populations.
