Evidence for intragenic recombination within a novel genetic marker that distinguishes mussels in the Mytilus edulis species complex.

abstract：:The importance of sexual selection in population divergence is of much interest, mainly because it is thought to cause reproductive isolation and hence could lead to speciation. Sexually selected traits have been hypothesized to diverge faster between populations than other traits, presumably because of differences in...
