A blue colour flower plant denoted by BB is crossbred with a white colour flower plant denoted by bb.(a) State the colour of flower you expect in their F1 generation plants.(b) What must be the percentage of white flower plants in F2 generation if flowers of F1 plants are self- pollinated?(c) State the expected ratio of the genotypes BB and Bb in the F2 progeny.

(a) In the F1 generation, the plants will have blue coloured flowers as B (blue) colour flower is dominant over b (white) colour.

(b) In F2 generation, 25% of total flowers are white (bb) in colour when plants are self-pollinated.

(c) The expected ratio of the genotypes BB and Bb in the F2 generation will be BB: Bb = 1: 2.
