Figure 1. Goodness-of-fit (following Pritchard et al., 2000) as a function of group number K in (a) the first cycle inbred panel and (b) the whole inbred panel. Average estimated goodness-of-fit over 10 independent outputs are indicated with a solid line. Structure options are "Admixture model," "allele frequency correlated," "infer alpha," and "separate alpha for each population." Inbred lines were considered as haploid organisms to relax the Hardy–Weinberg condition on group definition.
