Breakdown of sporophytic self-incompatibility: Diploids versus tetraploids

The paper investigates whether sporophytic self-incompatibility breaks down more easily in tetraploid compared to diploid populations, finding that dominance relationships significantly influence this outcome.

The contribution of non-additive genetic effects to the genetic variance of polyploid species.

This study investigates how genome doubling affects genetic variance in polyploid species, finding that genetic variance generally decreases, though non-additive effects can increase diversity in some cases.

Autopolyploid establishment under gametophytic self-incompatibility: the impact of self-fertilization and pollen limitation

This study investigates how selfing rates and pollen limitation affect tetraploid establishment under gametophytic self-incompatibility.

The effects of ploidy and mating system on the evolvability of populations: theoretical and empirical investigations

This study investigates how ploidy and mating system affect genetic variance in Erysimum incanum, finding empirical results contradict theoretical predictions.

Varying importance of postzygotic isolation in polyploid speciation? A survey of the triploid block strength, its causal mechanisms, and evolutionary consequences

This study surveys variation in triploid block strength across angiosperms and finds no significant impact of assessed factors on triploid seed viability, suggesting mixed roles in interspecies gene flow.

How environment and genetic architecture of unreduced gametes shape the establishment of autopolyploids

This paper challenges assumptions about polyploidy success by developing a theoretical model showing diploid adaptation, not tetraploid fixation, drives adaptation to new environments.

Strength of purifying selection on the amino-acid sequence is associated with the amount of non-additive variance in gene expression.

The study finds that genes with higher non-additive variance in expression show stronger purifying selection and lower synonymous variation in Arabidopsis lyrata.
