Inbreeding depression, the reduced fitness of the offspring of related individuals, can affect
males and females differently. Although a comprehensive theoretical framework describing …

The physiological costs of inbreeding in wild animals are well-documented, but the potential
cognitive costs of inbreeding have received far less attention. A growing body of evidence …

Sexual selection is a potent evolutionary force that has been shown to vary in strength and
direction depending on demographic factors such as density and sex ratio. However, the …

Basic models of mating-system evolution predict that hermaphroditic organisms should
mostly either cross-fertilize, or self-fertilize, due to self-reinforcing coevolution of inbreeding …

The genetic composition of an individual can markedly affect its survival, reproduction, and
ultimately fitness. As some wildlife populations become smaller, conserving genetic diversity …

The persistence of an invasive species is influenced by its reproductive ecology, and a
successful control program must operate on this premise. However, the reproductive …

Abstract The Pacific oyster (Crassostrea gigas) is widely cultured worldwide. Because
intercrossing inbred strains improves yield (heterosis), development of inbred lines is …

Inbreeding often causes a decline in biological fitness, known as inbreeding depression. In
genetics study, inbreeding coefficient f gives the proportion by which the heterozygosity of …

Sex allocation theory predicts that simultaneous hermaphrodites evolve to an evolutionary
stable resource allocation, whereby any increase in investment to male reproduction leads …

Assortative mating by size has been argued to be widespread in the animal kingdom.
However, the strength of size-assortative mating is known to vary considerably between …
