What is the deeper reason for increased variation in offspring during sexual reproduction?
Answer and explanation
Correct answer: Formation of new combinations of genetic information from two parents
The governing concept is genetic recombination in sexual reproduction. A child receives hereditary material from two parents, and the combination of their alleles is not an exact copy of either parent. Independent assortment and the random union of gametes can produce new combinations, increasing variation among offspring. Option A is correct; B describes copying rather than sexual reproduction, while C and D are biologically incorrect.
