Answer:

1/4 or 25% chance of expressing recessive genes

Step-by-step explanation:

Punnett Square ( Dominant B, recessive b)

~ B | b

B | BB | Bb

b | Bb | bb

1/4 or 25% chance of hom0zygous dominant (hom0zygous dominant)

1/2 or 75% chance of expressing dominant gene (heterozygous with recessive gene hidden)

1/4 or 25% chance of expressive recessive gene (hom0zygous recessive)
