The epistatic interaction between the second and third chromosomes of D. melanogaster was quantified in male mating activity under no competition among males. The mean mating activity of the two-chromosome homozygote was 0.517±0.064. The expected value under a multiplicative model was 0.509±0.054. Coefficient of interaction, I, was calculated to be 0.008±0.129. k statistic, a new measure of epistasis devised by Seager and Ayala (1982), was 0.029±0.027, which is not significantly different from zero. It is concluded that there is no interchromosomal interaction between two major autosomes in male mating activity.
