Example likelihood surfaces for individual tiger salamander hybrids. Joint maximum likelihood surfaces for three hybrid tiger salamanders from Bluestone Pond (Figure 3A). (A) and (B) are the individuals with the lowest and highest estimated interclass heterozygosity, respectively. (C) is a random draw from the few individuals classified as “F2-like” because the MLE is consistent with S = H
= 0.5. Each level of shading represents two log-likelihood units.
