Answer 1

1. When a population is separated by a geographical boundary it leads to genetic divergence due to reproductive isolation which helps the group acquire different triats than the original population.

2. In postzygotic barrier in which hybrid zygotes fail to mature normally which reduces the ability of the hybrid offspring to reproduce normally. Other barriers would be which prevents fertilization from occuring. They are evolutionary mechanisms or behaviors and physiological processes critical for speciation.

3. Phylogenetic tree represents evolutionary relationships among organisms and shows how species are related to each other in which species which have common ancestory are closely related while species which are unrelated have different ancestory.
