f1dr

Estimates double reduction in F1 populations by maximum likelihood.

Inference concerning equilibrium and random mating in
autopolyploids. Methods are available to test for equilibrium
and random mating at any even ploidy level (>2) in the presence
of double reduction at biallelic loci. For autopolyploid populations
in equilibrium, methods are available to estimate the degree of
double reduction. We also provide functions to calculate genotype
frequencies at equilibrium, or after one or several rounds of
random mating, given rates of double reduction. The main function is
hwefit(). This material is based upon work supported by the
