If an offspring resembles its parents but is not exactly identical, what is the correct reason?

Answer and explanation

Correct answer: Both heredity and variation

The governing concept is the combined action of heredity and variation. Heredity transfers genetic information from parents, producing resemblance. During reproduction and genetic copying, differences can arise through recombination or small copying changes, producing variation. Therefore option B explains both similarity and difference. Food, soil, or weather alone cannot account for the inherited pattern in offspring.
