If an offspring shows both similarity to and difference from its parents, what is the most correct reason?

Answer and explanation

Correct answer: Heredity produces similarity, while new chromosome combinations produce differences

The governing concept is the relationship between heredity and variation. Offspring inherit genetic information from both parents, so many characteristics resemble those of the parents. During reproduction, chromosomes and genes are combined in new arrangements, and small changes may also arise, producing differences. Therefore option A is correct. The other choices deny inheritance or incorrectly claim that food alone determines every trait.
