Question

By cross-breeding a tiger and a lion, a hybrid animal was created, but was infertile. Which evolutionary barrier caused the infertile offspring?
A.Prezygotic barrier
B.Postzygotic Barrier
C.Behavioral Barrier

Answer 1

The correct answer to this question is this one: B.Postzygotic Barrier
By cross-breeding a tiger and a lion, a hybrid animal was created, but was infertile. The evolutionary barrier that caused the infertile offspring is called the postzygotic barrier. Hope this helps answer your question.

Answer 2

Answer:

The correct answer would be B. post-zygotic barrier.

Reproductive isolation is a type of evolutionary mechanism by which inter-breeding between organisms of two species is prevented.

It includes pre and post zygotic barriers.

Pre-zygotic barriers include methods which prevent mating of two organisms.

In contrast, post-zygotic barriers are those by which mating occurs but the hybrid either is sterile or not viable or both.

Thus, infertile offspring of tiger and lion would be a type of post-zygotic barrier.
