Patterns of reproductive isolation in a haplodiploid mite, Amphitetranychus viennensis: prezygotic isolation, hybrid inviability and hybrid sterility

open access: yesBMC Ecology and Evolution, 2021
Background Evolution of reproductive isolation is an important process, generating biodiversity and driving speciation. To better understand this process, it is necessary to investigate factors underlying reproductive isolation through various approaches

Post‐pollination barriers contribute to coexistence of partially pollinator‐sharing Arisaema species (Araceae)

open access: yesEcology and Evolution, 2023
Reproductive isolation plays an important role in maintaining the species integrity of sympatric close relatives. For sympatric Arisaema species, interspecific gene flow is expected to be effectively prevented by pre‐pollination barriers, particularly ...

Reproductive Isolation during Domestication [PDF]

open access: yesThe Plant Cell, 2012
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 ...

Immunoglobulin genes, reproductive isolation and vertebrate speciation. [PDF]

open access: yesImmunol Cell Biol, 2022
AbstractReproductive isolation drives the formation of new species, and many genes contribute to this through Dobzhansky–Muller incompatibilities (DMIs). These incompatibilities occur when gene divergence affects loci encoding interacting products such as receptors and their ligands.

Predicting how pollinator behavior causes reproductive isolation. [PDF]

open access: yesEcol Evol, 2022
AbstractPollinator behavior is an important contributor to plants speciation, yet how variation in pollinator behavior causes variation in reproductive isolation (RI) is largely uncharacterized. Here I present a model that predicts how two aspects of pollinator behavior, constancy and preference, contribute to a barrier to reproduction in plants.

Reproductive isolation in Saccharomyces [PDF]

open access: yesHeredity, 2008
Although speciation is one of the most interesting processes in evolution, the underlying causes of reproductive isolation are only partially understood in a few species. This review summarizes the results of many experiments on the reproductive isolation between yeast species of the Saccharomyces sensu stricto group. Hybrids between these species form

QTL mapping reveals the genetic architecture of loci affecting pre- and post-zygotic isolating barriers in Louisiana Iris

open access: yesBMC Plant Biology, 2012
Background Hybridization among Louisiana Irises has been well established and the genetic architecture of reproductive isolation is known to affect the potential for and the directionality of introgression between taxa. Here we use co-dominant markers to

Evolutionarily diverged regulation of X-chromosomal genes as a primal event in mouse reproductive isolation. [PDF]

open access: yesPLoS Genetics, 2014
Improper gene regulation is implicated in reproductive isolation, but its genetic and molecular bases are unknown. We previously reported that a mouse inter-subspecific X chromosome substitution strain shows reproductive isolation characterized by male ...

Evolution of reproductive isolation in plants [PDF]

open access: yesHeredity, 2008
Reproductive isolation is essential for the process of speciation and much has been learned in recent years about the ecology and underlying genetics of reproductive barriers. But plant species are typically isolated not by a single factor, but by a large number of different pre- and postzygotic barriers, and their potentially complex interactions ...

MODELS OF EVOLUTION OF REPRODUCTIVE ISOLATION [PDF]

open access: yesGenetics, 1983
ABSTRACT Mathematical models are presented for the evolution of postmating and premating reproductive isolation. In the case of postmating isolation it is assumed that hybrid sterility or inviability is caused by incompatibility of alleles at one or two loci, and evolution of reproductive isolation occurs by random fixation of different ...
