Answer: The correct option is B. To determine if one trait could affect the inheritance of other trait.
The dihybrid cross is a cross between the two parents who have difference in two pairs of the alleles.
In the experiment of the dihybrid cross, during the first meiotic division the homologous pair of the chromosomes aligned randomly before getting separated from each other. The separation of the chromosomes leads to independent assortment. The four cells which are formed during the second meiotic division are developed into the haploid gametes.
The relationship data of the dominance for each trait between the alleles was available with Mendel. The purpose of the dihybrid cross was to determine the type of relationship that existed between the pair of alleles.
The result of the experiment of the dihybrid cross was the law of independent assortment according to which the formation of gametes the segregation of alleles of both the pairs of alleles are independent of each other.
