The purpose of Mendel’s dihybrid cross experiment was to find out if one trait can affect the inheritance of other traits.

Option D

Explanation:

In every living organism there are innumerable characters and each of those character is regulated by alleles. Alleles are basically a form of gene.  Mendel carried out dihybrid cross experiment  in order to understand whether or not a pair of allele affects the inheritance of another pair of alleles. Mendel conducted this experiment by using three steps: Firstly he selected parents and obtained the pure lines. His next step was Emasculation , Dusting and Raising F1 Generation, and lastly he inbreed-ed F1 hybrids so that it can produce F2 generation. And his experiment turned out to be a success.
