Question

What did the geneticists get right about evolution? What did they fail to understand?

A)Geneticists understood how offspring transmitted traits to their parents, and where mutations come from. They failed to understand how the environment interacted with these traits to promote or impede reproduction among organisms.

B)Geneticists understood how parents transmitted traits to their offspring, and where mutations come from. They failed to understand how the environment interacted with these traits to promote or impede reproduction among organisms.

C)Geneticists understood how parents transmitted traits to their offspring, and where mutations come from. They failed to understand the origin of new traits.

D)Geneticists understood how parents transmitted traits to their offspring, and where new species come from. They failed to understand how the environment interacted with these traits to promote or impede reproduction among organisms.

Explanation / Answer

Ans: B: Geneticists understood how parents transmitted traits to their offspring, and where new species come from. They found that the chromosome contain gene for particular traits and by the fusion of egg and sperm, these traits are transmitted to offsprings. And they understtod that mutation is part of evolution and the key reason for new traits.

Somehow, they failed to understand how environment interacted with these traits to promote or impede reproduction among organisms.
