title: Male-mediated effects on female meiotic recombination.
abstract: Recombination rates vary owing to an individual's genetic composition and/or its environmental condition. Yet, the effects of mating partner on recombination rates have not been considered. Here, I document a previously undescribed, male-mediated effect on female recombination rates. After crossing females to males from different genetic backgrounds, I observed a significant difference in proportion of recombinant offspring based on the genetic background of the father (P= 0.0292; df = 3; F= 3.07). Genetic variation in male ability to affect recombination rate in their mates suggests the potential for sexual conflict on optimal proportion of recombinant offspring, perhaps leading to changes in population-level recombination rates with varying levels of sexual selection.
