To prevent inbreeding, many angiosperms exhibit self-incompatibility (SI), which ensures that only pollen from a different plant can fertilize the ovules. There are different SI mechanisms, but all of them consist of tightly linked male and female expressed genes, which together …

WebAngiosperms exhibit a vast array of reproductive strategies, including both asexual and sexual, the latter of which includes both self-fertilization and cross-fertilization. Asexual reproduction and self-fertilization are important reproductive strategies in a variety of situations, such as when mates are scarce or when the environment remains ...
WebFeb 1, 2012 · Angiosperms have developed self-incompatibility (SI) as a genetic system to prevent inbreeding and thus promote outcrossing to generate genetic diversity. SI is based on the self/non-self discrimination between male and female.
