Question

In pea plants pink flowers are dominant to blue if a heterozygous pink flowered plant is crossed with a blue flowered plant what ratio of pink and blue flowered plants would you expect in F1 generation

Answer 1

Answer:

The cross can be represented as shown in the figure.

a) The color of flowers in F1 progeny is blue.

b) The phenotypic ratio of blue and white flowers in F2 generation is 3 : 1

So, percentage of plants bearing white flowers in F2  generation = 1/4 x 100 = 25%

c) The ratio of genotype BB and Bw in F2 progeny: 1: 2

Hope this helps!
