Which of the following pairs of genotypes represent a dihybrid cross?

a. AaBBCc x aabbcc

b. AaBb x aaBB

c. Aa x aa

The correct assertive is letter B. AaBb x aaBB

Explanation:

Hybrid crossover is characterized by comparing two simultaneous characters. As an example we have the height of a plant and the colors of peas, as in the case of Mendel's experiment to determine how much is transmitted to the offspring.

To illustrate, let's imagine that we have two types of peas: one has tall and purple flowers and the other is a dwarf plant and white flowers, with the tall plant genotype being "AA" and the dwarf plant genotype "aa" also whereas, the genotype of the plant with purple flower "PP" and white flower "pp".

Knowing that the genotype of a tall purple plant is AAPP and a dwarf white-flowered plant is aapp, when we cross, this crossing is called a hybrid cross like the following: AAPP x aapp.
