Histone Transition During Spermiogenesis Is Absent in Segregation Distorter Males of Drosophila melanogaster

Abstract
Males homozygous for the segregation distorter chromosome are often sterile or nearly sterile as a result of the dysfunction of virtually all their sperm. Spermatid bundles from such males do not exhibit the normal transition from lysine-rich to arginine-rich histones.
