Question

Read the following passage and answer the following question.
A group of 10 newly hatched chicks was separated into two smaller groups containing five chicks each. One group (Group A) was left with the mother hen, the other group (Group B) was taken shortly after hatching and kept with a mother goose. The chicks in Group A displayed normal behavior and followed the mother hen around. The chicks in Group B followed the mother goose around and exhibited goose like behavior, such as swimming. After one week, Group B was reunited with the mother hen, but ignored her, and instead continued to follow the mother goose around the barnyard. If exposed to a mother pig during the period shortly after hatching, the chicks in Group B would exhibit

• A. Pig like behaviour
• B. Goose like behaviour
• C. Chick like behaviour
• D. Unique behaviour
• E. Unknown behaviour

Answer 1

The correct option is A Pig like behaviour

A form of learning that occurs during a brief genetically determined critical period shortly after birth is called as imprinting. Because the chicks learnt to follow mother goose and mother hen just after birth; it is imprinting. If they were exposed to mother pig shortly after hatching, they would exhibit pig like behavoiur.

Thus, the correct answer is option (A).
