What is reproductive isolation? - PMC - PubMed Central (PMC)
Reproductive isolation (RI) is a core concept in evolutionary biology. It has been the central focus of speciation research since the modern synthesis and is the basis by which biological species are defined.
Reproductive isolation - Understanding Evolution
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.
18.2B: Reproductive Isolation - Biology LibreTexts
2024年11月23日 · 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 - Wikipedia
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.
Isolation of Species: Meaning and Mechanisms | Biology
In this article we will discuss about the meaning and mechanisms of isolation of species. The first step in the development of a new species is isolation. A population should split up into two or more separate demes each with its own gene pool. These demes must be …
Temporal isolation | Definition & Examples | Britannica
Temporal isolation, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from …
22.2: Natural Selection and Reproductive Isolation - Biology …
In isolation, changes in the gene pool can occur through some combination of natural selection, genetic drift, and founder effect. These factors may produce distinct subpopulations on the different islands.

Geographic isolation facilitates the evolution of reproductive ...
Geographic isolation is known to contribute to divergent evolution, resulting in unique phenotypes. Oftentimes morphologically distinct populations are found to be interfertile while reproductive isolation is found to exist within nominal ...
Evolution and molecular bases of reproductive isolation - PMC
Reproductive isolation is interesting to biologists because it gets at the fundamental question: what is a species and how is it formed? Reproductive isolation (RI) allows for the maintenance of diversity and forms the basis of the Biological Species Concept.
