“…Strong linkage to A M is expected for alleles on the same autosome because recombination is low or nonexistent in house fly males ( Hiroyoshi 1961 ; Hamm et al 2015 ), but see Feldmeyer et al (2010) . It is possible that A M chromosomes invaded house fly populations because of selection on phenotypic effects of either the autosomal M loci themselves or alleles linked to M -factors ( Franco et al 1982 ; Tomita and Wada 1989a; Kozielska et al 2006 ; Feldmeyer et al 2008 ). M variants are known to have subtle phenotypic effects, which include differential splicing and expression of SD pathway genes between Y M and A M males ( Schmidt et al 1997 ; Hediger et al 2004 ; Siegenthaler et al 2009 ).…”

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 (YM), which is probably the ancestral state. An M factor on the third chromosome (IIIM) has reached high frequencies in multiple populations across the world, but the evolutionary forces responsible for the invasion of IIIM are not resolved. To test whether the IIIM 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 YM or IIIM chromosome have different gene expression profiles. We find that more genes are differentially expressed between YM and IIIM males in testis than head, and that genes with male-biased expression are most likely to be differentially expressed between YM and IIIM males. We additionally find that IIIM males have a “masculinized” gene expression profile, suggesting that the IIIM chromosome has accumulated an excess of male-beneficial alleles because of its male-limited transmission. These results are consistent with the hypothesis that sex-specific selection acts on alleles linked to the male-determining locus driving evolutionary turnover in the sex determination pathway.

“…These autosomal (more precisely, non‐Y) M factors seem to have appeared relatively recently and may be spreading, replacing the standard XY system in many locations (see Franco et al. , 1982; Tomita & Wada, 1989b). Intriguingly, the frequency of autosomal M factors seems to decrease with latitude and altitude: northern and high altitude populations are usually dominated by the standard XY system.…”

Sex determining (SD) mechanisms are highly variable between different taxonomic groups and appear to change relatively quickly during evolution. Sex ratio selection could be a dominant force causing such changes. We investigate theoretically the effect of sex ratio selection on the dynamics of a multi‐factorial SD system. The system considered resembles the naturally occurring three‐locus system of the housefly, which allows for male heterogamety, female heterogamety and a variety of other mechanisms. Sex ratio selection is modelled by assuming cost differences in the production of sons and daughters, a scenario leading to a strong sex ratio bias in the absence of constraints imposed by the mechanism of sex determination. We show that, despite of the presumed flexibility of the SD system considered, equilibrium sex ratios never deviate strongly from 1 : 1. Even if daughters are very costly, a male‐biased sex ratio can never evolve. If sons are more costly, sex ratio can be slightly female biased but even in case of large cost differences the bias is very small (<10% from 1 : 1). Sex ratio selection can lead to a shift in the SD mechanism, but cannot be the sole cause of complete switches from one SD system to another. In fact, more than one locus remains polymorphic at equilibrium. We discuss our results in the context of evolution of the variable SD mechanism found in natural housefly populations.
