Question

Indicate, as true or false, whether each of the following statements about species is a component of the biological species concept.
A. Their reproductive isolation from each other is complete.
B. They are unable to produce hybrid offspring upon interbreeding.
C. They shared a common ancestor recently in evolutionary time.

Answer 1

Their reproductive isolation from each other is complete: False  

They are unable to produce hybrid offspring upon interbreeding: True  

They shared a common ancestor recently in evolutionary time: False  

Explanation:

A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.  

This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
