This program calculates a hybrid index for individuals of unknown ancestry. The index is based on information from molecular markers and uses maximum-likelihood to estimate the proportion of alleles that were inherited from one of two hybridizing parental species.

This is a software package for mapping components of isolation in hybrids. The software is in development and initial release will be in spring 2009. It is an R-package that implements various methods for the analysis of gene introgression in hybrid zones (Gompert and Buerkle 2009, Molecular Ecology).
