Question

Flower color in snapdragons is an example of incomplete dominance. if a red-flowered plant is crossed with a white-flowered plant, the f1 generation has pink flowers. if a pink-flowered plant is crossed with another pink-flowered plant, the expected progeny plants will be __________.

Answer 1

c. incomplete dominance

Step-by-step explanation:

The production of pink flowers results from incomplete dominance in a genetic cross between a red flowering plant and a white flowering plant. The expression of the recessive allele is not completed blocked by the expression of the dominant allele.

Answer 2

the expected progeny plants of the F2 generation (pink flower x pink flower) will be:

1/4 = 25% RR (homozygous dominant)- phenotype: red
2/4 = 50% Rr (heterozygous) phenotype: pink
1/4 = 25% rr (homozygous recessive)phenotype: white

R- red
r- white
