Transcriptome Differences between Alternative Sex Determining Genotypes in the House Fly, Musca domestica.

ABSTRACT: Sex determination evolves rapidly, often because of turnover of the genes at the top of the pathway. The house fly, Musca domestica, has a multifactorial sex determination system, allowing us to identify the selective forces responsible for the evolutionary turnover of sex determination in action. There is a male determining factor, M, on the Y chromosome (Y(M)), which is probably the ancestral state. An M factor on the third chromosome (III(M)) has reached high frequencies in multiple populations across the world, but the evolutionary forces responsible for the invasion of III(M) are not resolved. To test whether the III(M) chromosome invaded because of sex-specific selection pressures, we used mRNA sequencing to determine whether isogenic males that differ only in the presence of the Y(M
