Genetic basis for remating in Drosophila melanogaster. IV. A chromosome substitution analysis.

Drosophila melanogaster lines previously selected for fast and slow return of female receptivity were subjected to a chromosome substitution analysis. Chromosomal effects on direct response to selection were distinctively different between selection lines derived from two different base populations. All three chromosomes tested affect the trait in the JEFFERS selection lines. In contrast, only chromosome II was found to have a main effect in the COMP selection lines. Significant interactions between chromosome II and the other chromosomes were also found in both of the selection lines. All of the components of virgin fly mating behavior measured were affected by chromosome II.
