Charles Darwin recognized that flowering plants have an unrivalled diversity of sexual
systems. Determining the ecological and genetic factors that govern sexual diversification in …

▪ Abstract Mixed mating, in which hermaphrodite plant species reproduce by both self-and
cross-fertilization, presents a challenging problem for evolutionary biologists. Theory …

Levels of neutral genetic diversity in populations subdivided into two demes were studied by
multi-locus stochastic simulations. The model includes deleterious mutations at loci …

Wind pollination (anemophily) of angiosperms probably evolved from insect pollination
(entomophily) in response to pollinator limitation and changes in the abiotic environment …

We review and analyze the available literature on the frequency and distribution of self-
incompatibility (SI) among angiosperms and find that SI is reported in more than 100 families …

▪ Abstract Inbreeding depression critically influences both mating system evolution and the
persistence of small populations prone to accumulate mutations. Under some …

The evolution of self-fertilization in hermaphrodites is opposed by costs that decrease the
value of self progeny relative to that of outcross progeny,,. However, self-fertilization is …

Baker's Law states that it is more likely for self‐compatible than for self‐incompatible
individuals to establish sexually reproducing colonies after long‐distance dispersal …

A compound hypothesis positing that self‐fertilization is an evolutionary dead end conflates
two distinct claims: the transition from outcrossing to selfing is unidirectional; and the …

Background The field of plant mating-system evolution has long been interested in
understanding why selfing evolves from outcrossing. Many possible mechanisms drive this …
