1.	Question : A blue colour flower plant denoted by BB is crossbred with a white colour flower plant denoted by ww. (i) State the colour of flower we would expect in their F_(1)progeny. (ii) Write 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 : Bw : ww in the F_(2) progeny.
Answer» SOLUTION :(i) `F_(1)` generation yields only blue FLOWERING plants. (Bw). (ii) On self-breeding the `F_(1)`generation plants, both blue flowered and white flowered plants APPEARED in the RATIO of 3:1. It shows that the factors or traits for blue flower are dominant over the traits for white flower. (iii) GENOTYPES in `F_(2)`progeny is 1:2:1
