Answer 1

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
