Sex-ratio drive, which has been documented in several Drosophila species, is induced by X-
linked segregation distorters. Contrary to Mendel's law of independent assortment, the sex …

During speciation, sex chromosomes often accumulate interspecific genetic incompatibilities
faster than the rest of the genome. The drive theory posits that sex chromosomes are …

The chromosomal distribution of genes with sex-biased expression is often nonrandom, and
in species with XY sex chromosome systems, it is common to observe a deficit of X-linked …

Stalk-eyed flies in the genus Teleopsis carry selfish genetic elements that induce sex ratio
(SR) meiotic drive and impact the fitness of male and female carriers. Here, we assemble …

Widespread loss of genes on the Y is considered a hallmark of sex chromosome
differentiation. Here we show that the initial stages of Y evolution are driven by massive …

By distorting M endelian transmission to their own advantage, X‐linked meiotic drive
elements can rapidly spread in natural populations, generating a sex‐ratio bias. One …

Meiotic drive elements are a special class of evolutionarily “selfish genes” that subvert
Mendelian segregation to gain preferential transmission at the expense of homologous loci …

Mechanisms of sex chromosome dosage compensation (SCDC) differ strikingly among
animals. In Drosophila flies, chromosome-wide transcription is doubled from the single X …

Segregation Distorter (SD) is a selfish, coadapted gene complex on chromosome 2 of
Drosophila melanogaster that strongly distorts Mendelian transmission; heterozygous …

Sex differences in dioecious animals are pervasive and result from gene expression
differences. Elevated sexual selection has been predicted to increase the number and …
