This Punnett square shows flower color inheritance in snapdragons. What is the expected ratio of red flowers to pink flowers to white flowers in the F2 generation?

A Punnett square showing color inheritance in snapdragons

A. 1 red: 2 pink: 1 white
B. 9 red: 3 pink: 1 white
C. 4 red: 1 white

Punnett Squares have been used to calculate the genotype and phenotype traits of an organism in the given generation.

The inheritance of snapdragons in the F2 generation is 1 red: 2 pink: 1 white.

The snapdragons show incomplete dominance, in which the parental contribution gives rise to the progeny that have an intermediate phenotype of both the parent.

Let the F1 progeny of snapdragons flower be R (red) and W (white).

The self-cross between the F1 progeny is given in the attachment below.

Thus, the F2 progeny will have 1 red, 2 pink, and 1 white flower due to incomplete dominance.

To know more about incomplete dominance, refer to the following link:

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
