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

The genetic architecture underlying the evolution of a rare piscivorous life history form in brown trout after secondary contact and strong introgression [PDF]
, 2018 Identifying the genetic basis underlying phenotypic divergence and reproductive isolation is a longstanding problem in evolutionary biology. Genetic signals of adaptation and reproductive isolation are often confounded by a wide range of factors, such as

The roles of inter- and intra-sexual selection in behavioral isolation between native and invasive pupfishes [PDF]
, 2017 Male-male competition and female mate choice may both play important roles in driving and maintaining reproductive isolation between species. When previously allopatric species come into secondary contact with each other due to introductions, they ...

BMC Evolutionary Biology, 2008 Background An open, focal issue in evolutionary biology is how reproductive isolation and speciation are initiated; elucidation of mechanisms with empirical evidence has lagged behind theory.

Nature Communications, 2021 How ecological divergence causes reproductive isolation between populations in close contact remains poorly understood at the genomic level. This study presents a clinal investigation based on whole-genome sequencing to characterize reproductive ...

Molecular evolution of candidate male reproductive genes in the brown algal model Ectocarpus [PDF]
, 2016 Background: Evolutionary studies of genes that mediate recognition between sperm and egg contribute to our understanding of reproductive isolation and speciation. Surface receptors involved in fertilization are targets of sexual selection, reinforcement,

Predicting how pollinator behavior causes reproductive isolation. [PDF]
Ecol 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.

Ectopic application of the repressive histone modification H3K9me2 establishes post-zygotic reproductive isolation in Arabidopsis thaliana [PDF]
, 2017 Hybrid seed lethality as a consequence of interspecies or interploidy hybridizations is a major mechanism of reproductive isolation in plants. This mechanism is manifested in the endosperm, a dosage-sensitive tissue supporting embryo growth.

Reproductive isolation in Saccharomyces [PDF]
Heredity, 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
