Question

In pea plants, the allele that codes for purple flower color (B) is dominant to the allele that codes for white flower color (b). A scientist crosses a heterozygous purple flowered pea plant (Bb) with a homozygous white flowered pea plant (bb).

The Punnett square representing the scientist’s cross is shown below. Drag and drop the picture that represents the phenotype that will be expressed for each potential genotype shown in the Punnett square.

Answer 1

- BB: Purple flowers
- Bb: Purple flowers
- bb: White flowers

(Note: This answer assumes complete dominance of the B allele over the b allele.)
