Motif length as a function of MS diversity. For all MS markers combined, the box plots compare the mean number (no) of alleles per locus (y-axis, blue), expected heterozygosity (He) (y-axis, red) and maximum repeat length (y-axis, green) across all motif lengths (x1°-axis), stratified API (x2°-axis). There were no significant correlations between motif length and the mean no of alleles per locus (panels i, ii) or mean He(panels iii, iv) in either API stratum. However, in the ≤0.05 API stratum there was a significant negative correlation between motif length and mean maximum repeat length (panel vi) (p <0.0001, ANOVA, bivariate fit). This correlation exists only as a trend for the >0.05 API stratum (panel v) (p = 0.349, ANOVA, bivariate fit).
