Question

For two traits T and P, what are the genotypes of the gametes that a heterozygote (TtPp) would produce?

a. TP, Tp, tP, tp

b. AB, Ab, Ba, ab

c. Tt, Tp, Pp, tP

d. Ab, AB,bA

Answer 1

Option a

Number of gametes produced is equal to, 2^n, Where n is the number of heterozygous gene pairs.

In the given genotype there are two heterozygous gene pairs, Tt and Pp.

So, gametes will be 2^2 = 4

Allele from one gene will combine with the allele from another gene to form a gamete.

Tt will produce T and t.

Pp will produce P and p.

Gametes will be TP, Tp, tP, tp.
