gerud 1.0: a computer program for the reconstruction of parental genotypes from progeny arrays using multilocus DNA data

We have no standard computer algorithm for the reconstruction of parental genotypes from the data generated by molecular studies of progeny arrays. Here I present a computer program that uses the multilocus genotypes of parents and offspring to reconstruct the genotypes of unknown parents contributing gametes to a progeny array for which one parent is known a priori . A second program performs simulations to assess the reliability of the algorithm under various scenarios. These programs will aid scientists engaged in parentage analyses, particularly in species with large clutches.
