Animals are usually expected to avoid mating with relatives (kin avoidance) as incestuous
mating can lead to the expression of inbreeding depression. Yet, theoretical models predict …

Cooperative breeding in birds typically occurs when offspring–usually males–delay
dispersal from their natal group, remaining with the family to help rear younger kin. Sex …

While extensive population genetic theory predicts conditions favoring evolution of self-
fertilization versus outcrossing, there is no analogous theory that predicts conditions favoring …

Inbreeding depression plays a major role in shaping mating systems: in particular,
inbreeding avoidance is often proposed as a mechanism explaining extra-pair reproduction …

The artificial propagation and release of Fenneropenaeus chinensis have been conducted
over the past three decades in China. To examine the current population genetic diversity …

Polyandry is often hypothesized to evolve to allow females to adjust the degree to which
they inbreed. Multiple factors might affect such evolution, including inbreeding depression …

The degree of inbreeding expressed within populations can profoundly shape evolutionary
dynamics. The degree to which individuals inbreed is frequently assumed to evolve in …

Inbreeding avoidance among interacting females and males is not always observed despite
inbreeding depression in offspring fitness, creating an apparent “inbreeding paradox.” This …

Inbreeding increases parent–offspring relatedness and commonly reduces offspring
viability, shaping selection on reproductive interactions involving relatives and associated …

One of the major decisions individuals of many species make when deciding who to mate
with is whether or not to inbreed. The prevailing theory is that individuals should avoid …
