1.	Question : 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.
Answer» SOLUTION :(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.
