Question

Sexual reproduction results in variation of the progeny from the parents. What do you think are the appropriate reasons?

(a) Since sexual reproduction involves only gene from a single parent which undergoes modifications to produce different traits in the progeny

(b) Sexual reproduction involves gene from both the parents which undergoes modifications to produce traits that vary from the parent

(c) It is due to variation in the time

(d) Parents decide the traits of the progeny and design them accordingly

This question was addressed to me in an international level competition.

This interesting question is from Living and Non Living topic in portion The Living World of Biology – Class 11

Answer 1

Right choice is (b) Sexual reproduction involves gene from both the parents which undergoes modifications to produce traits that vary from the parent

For explanation I would say: Sexual reproduction involves two parental organisms and the gene from both the organisms are involved which undergo modifications to produce new traits in the progeny.
