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

Which statement describes the offspring expected from this cross?

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
