Question

The P allele for purple is dominant to the p allele for white. If homozygous purple pea

plants are mated with homozygous white pea plants, all the offspring will be:
O heterozygous purple
O homozygous white
Olight pink heterozygous
O homozygous purple
O either purple or white

Answer 1

If homozygous purple pea plants are mated with homozygous white pea plants, all the offspring will be heterozygous purple.

Step-by-step explanation:

If homozygous purple pea plants are mated with homozygous white pea plants, all the offspring will be heterozygous purple. The P allele for purple color is dominant to the p allele for white color. This means that even though the offspring inherit one allele for purple color and one allele for white color, the dominant P allele masks the expression of the recessive p allele, resulting in the plants appearing purple.
