Question

Give an example of infertile offspring and fertile offspring​

Answer 1

Answer:

In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed. ... For example, when a female horse and a male donkey mate, they produce hybrid offspring called mules.

The offspring display traits and characteristics of both parents. The offspring of an interspecific cross very often are sterile, this hybrid sterility prevents the movement of genes from one species to the other, keeping both species distinct.
