Local mate competition (LMC), where closely related males compete for mates, in sub-divided populations selects for female biased offspring sex ratios. However, this relies on no competition occurring between sisters for shared resources, which breaks down under soft selection. Relatedness is another factor, which can be confounded with selection regime and may impact offspring sex ratios. In this talk, I will discuss the results of a selection experiment investigating sex allocation in related and unrelated populations of the spider mite Tetranychus urticae imposed to hard versus soft selection, under conditions of high LMC.
