Genetics of behavior: selection for mating ability in chickens.
MATING behavior in animals is complex and determined by diverse genetic and environmental factors. As one aspect of this behavior, mating frequency in chickens has received considerable attention ( UPP 1928; WOOD-GUSH 1956; MCDANIEL and CRAIG 1959; SIEGEL 1959; CARBAUGH, SCHEIN and HALE 1962; JUSTICE, MCDANIEL and CRAIG 1962). These reports, while not in agreement on the best procedures for the...
متن کاملSelection by parasites for clonal diversity and mixed mating.
On theoretical grounds, coevolutionary interactions with parasites can select for cross-fertilization, even when there is a twofold advantage gained by reproducing through uniparental means. The suspected advantage of cross-fertilization stems from the production of genetically rare offspring, which are expected to be more likely to escape infection by coevolving enemies. In the present study, ...
متن کاملSexual selection and mating systems.
Sexual selection is among the most powerful of all evolutionary forces. It occurs when individuals within one sex secure mates and produce offspring at the expense of other individuals within the same sex. Darwin was first to recognize the power of sexual selection to change male and female phenotypes, and, in noting that sexual selection is nonubiquitous, Darwin was also first to recognize the...

متن کاملInbreeding effects in a mixed-mating vine: effects of mating history, pollen competition and stress on the cost of inbreeding
Inbreeding depression is assumed to be a central factor contributing to the stability of plant mating systems. Predicting the fitness consequence of inbreeding in natural populations is complicated, however, because it may be affected by the mating histories of populations generating variation in the amount of purging of deleterious alleles. Furthermore, the level of inbreeding depression may d...
