Document Summary
Biological species concept: a group of individuals who can breed together are one species. If they cannot breed with other groups, than these groups are different species. A definition of species that focuses on reproductive capabilities, whereby different populations are considered to be in the same species if they organisms from naturally interbreed and produce fertile offspring. Rib (reproductive isolating barrier): barriers or mechanisms in organisms that reproductively isolate two individuals. Required through speciation and there are two types including ecological, temporal, behavior, mechanical, and gametic mortality prezygotic (pre-zygote, or incompatibility inviability, sterility, or producing fertile offspring. isolation) and post zygotic (post-zygote barriers with generation one hybrid breakdown). The genetic isolation of populations that may render them incapable of. List and define each of the specific pre-zygotic and post-zygotic. Barriers, providing an explanation of how each works. Ecological/habitat isolation: individuals mate in their preferred habitat, and therefore do not meet individuals of other species with different ecological preferences.
