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

Respuesta :

A. 1 red: 2 pink: 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.

How does Punnett Square show inheritance?

  • 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.
