Question

What type of gametes a NnPp genotype plant will produce?

Answer 1

NnPp genotype plant will produce 4 types of gametes regarding traits represented by genes N and P.

Explanation:

The plant having genotype NnPp is heterozygous for the two traits. N and n are dominant and recessive alleles, respectively of a single gene controlling a particular trait (not mentioned in question).
P and p are dominant and recessive alleles of another gene controlling another trait.

According to Mendel's law of independent assortment, the genes controlling two traits will segregate independently of each other.

Thus, the following 4 types of gametes will be produced by a plant with genotype NnPp.

1. NP 2. Np 3. nP 4. np.
