Longs heterogeneity test for admixture proportions in a single population.

Description

For hybrid individuals genotyped with diagnostic markers (one allele fixed in each parental lineage), the null hypothesis that variation in allele frequencies is explained by sampling and drift (no selection) is evaluated with a chi-squared test statistic.
