Question

Organisms can be classified in the same species by morphology and _____. variation, dichotomy, or reproductive isolation

Answer 1

The species will often divide into a group of individuals that have the potential to reproduce with each other, and they would be reproducing in an isolated area away from the other groups.

Answer 2

The correct answer would be reproductive isolation.

Species refer to the group of organisms which share common morphological features and can interbreed and produce a viable offspring.

Thus, the organisms of one species are reproductively isolated from the organisms of other species.

The reproductive isolation includes mechanical, behavioral, and physiological processes which prevent the interbreeding between organisms of different species.
