This study develops a unified Wright-Fisher model to analyze mutation fate on Y chromosomes and autosomes, showing overdominant mutations are more likely to fix on Y chromosomes due to segregation time effects.

This paper uses mathematical modeling and simulations to show how recombination suppression on sex chromosomes expands through sheltering from deleterious mutations and lower mutational load.

The paper shows that balancing selection promotes pseudo-overdominance and recombination suppression in genomic regions.

The paper shows that HD mating-type genes have lost function in three Microbotryum species, with PR genes controlling mating compatibility, and reports evolutionary strata from recombination suppression.

This study supports the theory that recombination suppression on sex chromosomes evolves due to lower-load advantages and sheltering effects from recessive deleterious mutations.
