Question

A pea plant with blue colour flower denoted by BB is crossbred with a pea plant with white flower denoted by BB
A) What is expected colors of the flower in F1 progeny?
b) what will be the Pencentage of plants bearing white flowers in F2 generation when the flowers in F1 plants were selfed?
C) state the expected ratio of the genotype BB and Bb in F2 progeny?​

Answer 1

Answer ⤵️

The cross can be represented as shown in the figure.

a) The color of flowers in F

1

progeny is blue.

b) The phenotypic ratio of blue and white flowers in F

2

generation is 3 : 1

So, percentage of plants bearing white flowers in F

2

generation = 1/4 x 100 = 25%

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