The coevolution of sexual imprinting by males and females
Sexual imprinting is the learning of a mate preference by direct observation of the phenotype of another member of the population. Sexual imprinting can be paternal, maternal, or oblique if individuals learn to prefer the phenotypes of their fathers, mothers, or other members of the population, respectively. Which phenotypes are learned can affect trait evolution and speciation rates. "Good gen...
متن کاملSexual selection in males and females.
Research on sexual selection shows that the evolution of secondary sexual characters in males and the distribution of sex differences are more complex than was initially suggested but does not undermine our understanding of the evolutionary mechanisms involved. However, the operation of sexual selection in females has still received relatively little attention. Recent studies show that both int...
متن کاملA Preference for a Sexual Signal Keeps Females Safe
Predation is generally thought to constrain sexual selection by female choice and limit the evolution of conspicuous sexual signals. Under high predation risk, females usually become less choosy, because they reduce their exposure to their predators by reducing the extent of their mate searching. However, predation need not weaken sexual selection if, under high predation risk, females exhibit ...

متن کاملSexual Behaviour: A Receptor for Sex Control in Drosophila Females
Male Drosophila manipulate the sexual behaviour of their female mating partners by release of a Sex-peptide, but how does this work? A G-protein-coupled receptor has now been identified which acts in the female flies to detect male Sex-peptide and trigger increased egg laying and reduced sexual receptivity.
