Epistasis affecting litter size in mice

Journal of Evolutionary Biology, 2004
Abstract Litter size is an important reproductive trait as it makes a major contribution to fitness. Generally, traits closely related to fitness show low heritability perhaps because of the corrosive effects of directional natural selection on the additive genetic variance.

THE INFLUENCE OF AGE ON LITTER-SIZE

Journal of Endocrinology, 1958
SUMMARY In three related strains of rats the numbers of fertile females have been found to fall with age and with the birth of successive litters. In thirty-five rats belonging to these three strains, each of which had a minimum of eight litters, the second litter was generally bigger than the first. From then on, however, litter-size

Evolution of litter size

Population Ecology, 1981
SummaryTheories on the evolution of litter size among organisms were reexamined. The competition theories, including that based on the r−K‐selection hypothesis, could not explain well why low‐fecundity strategies have often evolved in stressful environments such as mountain streams, deep sea and the antarctic, where interspecies competition is ...
