Sep 5, 2022 · Reproductive isolation (RI) is a core concept in evolutionary biology and the basis by which biological species are defined. Despite this, the term is used in different ways and efforts to quantify RI from data have used vastly different approaches.

The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation. They prevent members of different species from producing offspring , or ensure that any offspring are sterile.
Oct 31, 2023 · Reproductive isolation is a collection of mechanisms, behaviors, and physiological processes that prevent the members of two different species that cross or mate from producing offspring, or which ensure that any offspring that may be produced is not fertile.
Reproductive isolation. The environment may impose an external barrier to reproduction, such as a river or mountain range, between two incipient species but that external barrier alone will not make them separate, full-fledged species.
Jul 13, 2020 · Here, we discuss the efficacy of intrinsic postzygotic reproductive isolation as a barrier to gene flow by comparing intrinsic postzygotic barriers to other barriers, and discussing the factors that can influence the ability of intrinsic postzygotic reproductive barriers to prevent introgression.

Reproductive isolation is defined as processes that prevent individuals of different populations from mating, survival or producing fertile offspring. Reproductive isolation is critical for driving speciation and maintaining species identity, which has been a fundamental concern in evolutionary biology.
Feb 18, 2014 · We review current understanding of genome-wide effects of accumulating reproductive isolation and of genomic properties that influence the process of speciation.
