A pea plant with blue colour flower denoted by BB is cross-bred with a pea plant with white flower denoted by WW.
(i) What is the expected colour of the flowers in their `F_(1)` progeny?
(ii) What will be the percentage of plants bearing white flower in `F_(2)` generation, when the flowers of `F_(1)` plants were selfed?
(iii) State the expected ratio of the genotype BB and BW in the `F_(2)` progeny.

Explanation

(i) All the flowers in `F_(1)` generation will have dominant blue colour.
(ii) When `F_(1)` plants were selfed, the percentage of white flower in `F_(2)` generation will be `25%`.
(iii) Genotype of BB and BW in the `F_(2)` progeny are 1:2.
