No evidence of sex-ratio meiotic drive associated with the X-linked In(1)Be inversion in Drosophila melanogaster.

G3 (Bethesda, Md.) - 2 Sept 2026

An Madison E, Begun David J

Abstract excerpt

Sex-ratio (SR) X chromosomes are selfish genetic elements that increase the rate of X chromosome transmission in species with a heterogametic sex, violating Mendel's first law of segregation. In particular, heterogametic males carrying SR X chromosomes produce a greater number of X-bearing sperm than Y-bearing sperm and thus produce a greater number of female than male offspring. SR X chromosomes have been...
