Developmental changes favored by selection on a structure may result in developmental changes of the serially homologous structures at other positions in the body.

Although haplotype diversity is substantially reduced by selection on a microsatellite (i.e., H and K go down), effects on linked sequence diversity across the SFS are muted by the divergent ancestries/sequences of the surviving haplotypes.

Of primary interest were simulations in which drop out and disruptive behaviour were predicted by the same factor (X) (i.e. the drop-out occurred by selection on a predictor X in regression) and the degree of selection was varied between simulations.

We will now review the empirical evidence that polymorphism at recognition loci can be maintained by selection on a pleiotropic function in mate choice, with the aims of evaluating the relative importance of this mechanism across taxa and identifying gaps in our knowledge.
