Heterosis for viability, fecundity, and male fertility in Drosophila melanogaster: comparison of mutational and standing variation.

Genetics - 1 Mar 1998

Fry J D, Heinsohn S L, Mackay T F

Abstract excerpt

If genetic variation for fitness traits in natural populations ("standing" variation) is maintained by recurrent mutation, then quantitative-genetic properties of standing variation should resemble those of newly arisen mutations. One well-known property of standing variation for fitness traits is inbreeding depression, with its converse of heterosis or hybrid vigor. We measured heterosis for three fitness...
