The appearance of new combinations in a dihybrid cross supports which principle?

Answer and explanation

Correct answer: Independent assortment

A dihybrid cross follows two pairs of contrasting traits at the same time. Mendel’s principle of independent assortment states that, during gamete formation, the allele pair for one trait is distributed independently of the allele pair for another trait, when the relevant conditions apply. This produces combinations not seen in the original parents. Therefore option A is correct; blending, acquired-trait inheritance and chromosome destruction do not explain the result.
