Table 2 Information on the genetic structure of the population at generation 500 for 15 evolutionary runs under random versus m-trait mating (run numbers sorted on m separately for cases A. and B.; genetic structure of runs 1 and 15 for both cases illustrated in Fig. 2). The heterozygote deviance value (see Method section) is with respect to the parameter α, while the % variance explained by our principal components analysis (PCA) is with respect to the first two components

  1. aStatistical comparisons of A. and B. are highly significant for all three measures using a using a two-tailed non-parameteric Mann-Witney U test
  2. bA negative value implies a deficit of heterozygotes compared with Hardy-Weinberg equilibrium
  3. cNo value is given because insufficient genetic structure evolved in the parameter α to identify fewer than 5 distinct alleles
