What does the law of independent assortment show in a dihybrid cross?
Answer and explanation
Correct answer: Factors of two different traits may pass independently to offspring
Mendel’s law of independent assortment states that, during gamete formation, the allele pair for one trait can separate independently of the allele pair for another trait, provided the genes are not linked in a way that prevents independence. In a dihybrid cross this produces new combinations of traits, commonly reflected in the classic 9:3:3:1 ratio under ideal conditions. Thus option A is correct.
