The loss of Y-sperm in "sex ratio" (SR) males of Drosophila subobscura is compensated.

Abstract

In Drosophila subobscura sex ratio (SR) males, a mechanism compensating for the loss of Y-sperm is present since these males produced a higher number of female offspring than did males of three control strains. Moreover, the number of female offspring from SR-males was even higher (average 1719) than the number of female and male offspring together (average 1460) from T2, one of the control strains. The fertile life span of SR-males was found to lie between those of the control strains. The rate of insemination was the same for SR- and control males.
