TetraploidMap: Construction of a linkage map in autotetraploid species

TetraploidMap is a suite of Fortran 90 routines run from Microsoft Windows with a text-based input and output. TetraploidMap enables the user to assemble a linkage map from dominant and codominant (multiallelic) marker loci scored for the parents and full-sib progeny of a cross in an autotetraploid species. It includes routines for the inference of the parental genotypes, identification of linkage groups, two-point analysis to estimate the recombination frequency and LOD score between all pairs of marker in a linkage group, and locus ordering by simulated annealing.
