WebSeveral theoretical hypotheses have been proposed to explain the evolution of this bias: the resource competition hypothesis proposed by Greenwood, the local mate competition hypothesis, and the inbreeding avoidance hypothesis. Those hypotheses argued that the mating system should be the major factor explaining the direction of such bias.

However such effects have not been quantiﬁed in naturally complex mating systems that also encompass iteroparity, overlapping generations, sequential polyan-dry, and polygyny.
