Question

API plant with blue coloured flower denoted by BB is cross breed with API plant with white colour denoted by ww what is the expected colour of flour in their F1 progeny and see what will the present age of plants beard flower in F2 generation when the flower F1 plant where sulfide state the expert ratio of genotype bb and BW in the F2 progeny which is the dominant and which is the reccessive phenotype​

Answer 1

Answer:

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 progeny: 1: 2
