Question 1 of 15

In a pea plant, the allele for purple flowers (P) is dominant over the allele for white flowers (p). If a homozygous purple-flowered plant (PP) is crossed with a homozygous white-flowered plant (pp), what will be the genotype and phenotype of the offspring?

Select Your Answer:

All offspring will be heterozygous (Pp) and have purple flowers.

All offspring will be homozygous dominant (PP) and have purple flowers.

All offspring will be homozygous recessive (pp) and have white flowers.

Half of the offspring will be heterozygous (Pp) and have purple flowers, and the other half will be homozygous recessive (pp) and have white flowers.
