Question

The Punnett square above shows a cross between two sweet pea plants in Mendel's greenhouse. Both parents have blue flowers (Bb).

Answer 1

Answer:

 answer is 75% blue-flower and 25% white- flower pea plants

Explanation:

   As Blue is dominant trait,

both parents are heterozygous dominant  

Bb (father )   bb( mother )

So crossing between

     Bb        x     bb

                                              B                      b

                                B           BB                 Bb

                                 b           Bb                   bb

Offspring will be BB, Bb, Bb, bb

so 75% blue-flower and 25% white- flower pea plants
