Heritability of fitness in a wild mammal population.

摘要: Classical population genetics theory predicts that selection should deplete heritable genetic variance for fitness. We show here that, consistent with this prediction, there was a negative correlation between the heritability of trait and its association fitness in wild red deer (Cervus elaphus) no evidence significant total However, decline caused, at least part, by increased levels residual longevity and, hence, fitness: population, is known to be heavily influenced environmental factors. Other life history traits were not associated longevity, such as average annual breeding success, had higher heritabilities. Coefficients additive differed markedly traits, but highly skewed measures, male generally greater coefficients than morphometric traits. Finally, maternal effects range particularly females.
