Transitions in sex determination mechanisms through parental and sexual antagonism

Sex chromosomes carry the sex-determining locus, causing them to be differently transmitted to and from females and males. These differences lead them to be selected upon in different ways, and hence they are predicted to become enriched for sexually- and parentally-antagonistic genes. Sexually-antagonistic genes have opposing fitness effects in females versus in males; parentally-antagonistic genes have opposing fitness effects when inherited maternally versus paternally. Sexually-antagonistic selection can drive sex determination transitions, whereby an autosome pair becomes a sex chromosome pair in lieu of the ancestral sex chromosomes. Whether parentally-antagonistic selection can similarly drive sex determination transitions remains unknown. I present a model to investigate the potential for transitions in sex determination through parentally-antagonistic selection as compared to sexually-antagonistic selection. This model assumes an ancestral sex-chromosomal sex-determining locus ..., Data was generated using evolutionary genetic models written in R (v. 4.2.1).

**Description:** 

This data archive is structured in a way that it is clear how the various files are used to generate specific elements from the manuscript. This means that most data, analysis scripts, and output files are ordered into folders that correspond to specific figures from the main text or supplementary material. These folders are:
