Table 1 Sample sizes, means, and estimated variance components for all Crossover phenotypes for males (M) and females (F). Models were run for (A) individual gamete phenotypes and (B) the individual mean or composite phenotypes (i.e. Crossover interference) across all of their gametes. NFIDs is the number of unique focal individuals, Nobs is the total number of observations, VPis the phenotypic variance, h2is the narrow-sense heritability, pe2 is the proportion of permanent environmental variance (i.e., FID identity), and rA is the genetic correlations between males and females. Values in parenthesis are the standard errors. P-values for differences in female and male means are provided in table S1.
