Abstract
D. melanogaster males with 2 supernumerary Y chromosomes, i.e., triplo-Y males, are completely sterile. The mating behavior is normal, and spermatogenesis and spermiogenesis appear normal, but no sperm are transferred. Most, if not all, of the detrimental effects of a 3rd Y chromosome on male fertility are attributable to the long arm of the Y chromosome.This publication has 5 references indexed in Scilit:
