All of the following are examples of prezygotic genetic isolating mechanisms EXCEPT: Male fireflies of different species have differing flash patterns. A Three closely related orchid species flower on different days. B The progeny of a cross between two different lizard species fail to develop properly. C One species of snake lives in water and another is terrestrial. D Peeper frogs mate in April, and tree frogs mate in June.

B The progeny of a cross between two different lizard species fail to develop properly.

Explanation:

Two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

Option B states an example of post-zygotic barriers. The two different species of lizards have mated, but their progeny will either face severe developmental issues and/or be sterile.
