Appearance of new combinations in a dihybrid cross strengthens which Mendelian idea?
Answer and explanation
Correct answer: Independent assortment of different traits
A dihybrid cross follows two pairs of contrasting traits at the same time. During gamete formation, the allele pair for one trait can separate independently of the allele pair for the other, producing parental and non-parental combinations. This observation supports Mendel’s law of independent assortment. It does not support acquired inheritance, chromosome destruction, or permanent blending of traits.
