Snapdragons are popular garden plants that produce brightly colored flowers. When a plant that is homozygous for white flowers is crossed with a plant that is homozygous for red flowers, all offspring are pink. Snapdragons are an example of a plant that exhibits an inheritance pattern called incomplete dominance. Next, think about the gametes each parent plant will produce. List the allele in each gamete.

Aryana Burns · Answer 1

Incomplete dominance is an intermediate effect of the dominance where the allele for a trait does not express its complete effect of a paired allele as a result both the alleles show their equal effect on the trait.

The generations are produced having a third trait as observed in the case of snapdragon flowers. In the case of flowers

The allele which

1. Determines the red color will be - R

2. Determines the white color will be - r

The monohybrid cross will have parents with genotypes:

1. Red flower - RR

2. white flower-rr

The F₁ generation will have offsprings with genotype-

RR X rr = Rr (Pink flower)

The F₂ generation will have offsprings with-

Rr x Rr = RR, Rr and rr.
