Likelihood surfaces for codominant markers. Likelihood surfaces of ancestry (S) and interclass heterozygosity (HI) for 10 (A-C) and 40 (D-F) codominant biallelic loci with parental allele frequencies of 0.9 and 0.1. (A) and (D) are F1 hybrids with S = 0.5 and HI = 1.0; (B) and (E) are F2 hybrids (S = 0.5, HI = 0.5); (C) and (F) are homozygous recombinants (S = 0.5, HI = 0.0). Each level of shading covers two units of log-likelihood, so black is within 2 log-likelihood units of the maximum.
