Question

One experimenter cut the tails of parent rats , what could be the the traits in offsprings? Do the daughter rats contain tails or not? Explain your argument.

Answer 1

Answer:

The daughter rats would contain tail because by birth the parents had tail, so the daughter will have tail

Answer 2

Answer:

In the given experiment, it is observed that the daughter rats contain tails.

Explanation:

Characters or traits which are inheritable are passed on to the next generation, however, acquired traits are not inherited by the progeny. Information needs to be passed on to the germline cells for them to be expressed in the next generation.

In this case, the cut tail is an acquired trait and no gene is associated with it. In the daughter rats, the original gene coding for the tails are expressed and hence they have tails.
