Abstract
Males of Drosophila pseudoobscura carrying the sex-ratio chromosome (SR) were studied to determine the cause of X/O male progeny that they produce. It was found that among 3671 X/O progeny virtually all resulted from nullo-X sperm. The experiment also revealed a dramatic clustering of the frequency of X/O progeny among SR/Y males. This is interpreted to indicate that premeiotic events in the male germ line are the cause of nullo-X sperm.Entities:
