Population bottlenecks increase additive genetic variance but do not break a selection limit in rain forest Drosophila.

Genetics - 1 Aug 2008

van Heerwaarden Belinda, Willi Yvonne, Kristensen Torsten N, Hoffmann Ary A

Abstract excerpt

According to neutral quantitative genetic theory, population bottlenecks are expected to decrease standing levels of additive genetic variance of quantitative traits. However, some empirical and theoretical results suggest that, if nonadditive genetic effects influence the trait, bottlenecks may actually increase additive genetic variance. This has been an important issue in conservation genetics where it has...
