Detailed explanation-1: -Allopatric speciation (1) occurs when a species separates into two separate groups which are isolated from one another. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another.
Detailed explanation-2: -There are two major types of reproductive isolation. These are pre-zygotic barriers and post-zygotic barriers. Pre-zygotic describes reproductive barriers that occur before mating or fertilization. These can be physical or behavioral changes.
Detailed explanation-3: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.
