Reproductive isolation during domestication.
It has been hypothesized that reproductive isolation should facilitate evolution under domestication. However, a systematic comparison of reproductive barrier strength between crops and their progenitors has not been conducted to test this hypothesis. Here, we present a systematic survey of reproductive barriers between 32 economically important crop species and their progenitors to better unde...
متن کاملEvolution during Domestication
Domestication is a genetic selection process exerted – consciously or unconsciously – by humans to adapt wild plants andanimals to cultivation andherding, respectively. Because of this process, major crops and domesticated breeds arose,whichwere not only easier to cultivate or herd but also more appealing to consume or process for further uses. During domestication, plants and animals are subje...
متن کاملAsymmetric reproductive isolation during simultaneous reciprocal mating in pulmonates.
The generality of asymmetric reproductive isolation between reciprocal crosses suggests that the evolution of isolation mechanisms often proceeds in reciprocal asymmetry. In hermaphroditic snails that copulate simultaneously and reciprocally, asymmetry in premating isolation may not be readily detectable because the failure of the symmetric performance of courtship would prevent copulation from...
متن کاملReproductive isolation in Caenorhabditis briggsae
In sexual species, speciation occurs through the accumulation of genetic barriers to gene flow. In Caenorhabditis briggsae, one such barrier impedes gene flow between temperate strains and the tropical AF16 strain. Up to 20% of F2 progeny derived from crosses of AF16 to strains from the temperate clade exhibit a delayed development phenotype. This phenotype, which results from dysgenic interact...
متن کاملReproductive isolation grows on trees.
Despite rapid advances in the complementary fields of speciation genetics and molecular phylogenetics, little attention has been devoted to understanding how genetic changes associated with reproductive isolation accumulate across clades of species. We argue that comparative analyses of reproductive isolation QTL (quantitative trait loci) can generate unique insights into the underlying mechani...
