how does reproductive isolation cause speciation brainly

It prevents divergence.



Speciation, the formation of new and distinct species by splitting a single lineage into two or more genetically independent ones. Reproductive isolation separates the reproduction of one population into two populations. genetic incompatibilities between species that cause hybrid dysfunction) might arise long after successful speciation has occurred (Grant & Grant, 1997; Coyne & Orr, 2004; Bolnick & Near, 2005; Wiens, Engstrom & Chippindale, 2006), implying that these forms of reproductive isolation contribute little to the speciation process. For example, intrinsic postzygotic isolation (i.e. We need you to answer this question!

Hypotheses regarding how speciation begins differ in the role of geographic isolation and the origin of reproductive isolation (preventing populations from breeding with … How does reproductive isolation cause speciatation? How does reproductive isolation cause speciation? Reproductive isolation refers to a set of conditions, that can be psychological, ecological, genetic or behavioral, which do not allow animals of closely-related species to unite and mate.

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. Allopatry may start the process off, but the evolution of internal (i.e., genetically-based) barriers to gene flow is necessary for speciation to be complete. O C. It allows interbreeding.

O A. Reproductive isolation is a type of speciation. In reproductive isolation, there are strong reproductive barriers that keep the related species separate.

It reduces gene flow.

O D. It stops adaptive radiation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
O B.
Reproductive isolation.
