Popis:	Genetic variation among females is likely to influence the outcome of both pre- and post-copulatory sexual selection in Drosophila melanogaster. Here we use association testing to survey natural variation in 10 candidate female genes for their effects on female reproduction. Females from 91 chromosome two substitution lines were scored for phenotypes affecting pre- and post-copulatory sexual selection such as mating and remating rate, propensity to use sperm from the second male to mate, and measures of fertility. There were significant genetic contributions to phenotypic variation for all the traits measured. Resequencing of the 10 candidate genes in the 91 lines yielded 68 non-synonymous polymorphisms which were tested for associations with the measured phenotypes. Twelve significant associations (markerwise P
