Question

Which of the following is a genetic variation?

• A. Ability to play badminton
• B. Child born with a tail
• C. Ability to speak a foreign language
• D. All of these

Answer 1

The correct option is B Child born with a tail

Over the time, in the course of evolution, humans have lost their tail. But the genes which code for tail formation do exist in human beings and remain masked for most of the individuals. If by some mutation these genes get expressed, those humans will have a tail. This is a variation.
The ability to play badminton or to speak a foreign language are skills that an individual develops and are thus acquired characteristics.
