WebAllochronic speciation (also known as allochronic isolation, or temporal isolation) is a form of speciation (specifically ecological speciation) arising from reproductive isolation that occurs due to a change in breeding time that reduces or eliminates gene flow between two populations of a species. The term allochrony is used to describe the general ecological … Web22 de nov. de 2024 · Because the trait is heritable, offspring generally have the same trait as their parents. Therefore, the adaptive heritable trait tends to become more common in the population. This process is called natural selection. 9.
