Limits to adaptation in partially selfing species

This study examines how adaptation rates are affected by selfing and outcrossing in partially selfing species, finding that loss of weaker adaptive alleles during selective sweeps and reduced recombination effects limit adaptation in selfing organisms.

Coalescence with background and balancing selection in systems with bi- and uniparental reproduction: contrasting partial asexuality and selfing

The paper examines how background and balancing selection affect coalescent time in diploid systems with partial asexuality and selfing, finding stronger effects of background selection with lower sex rates.

Coalescent times and patterns of genetic diversity in species with facultative sex: effects of gene conversion, population structure and heterogeneity

The paper extends coalescent theory to facultative sexual species, showing gene conversion reduces genetic diversity and can reverse predictions when sex is rare.
