For any gene with a dominant allele P and recessive allele p, what proportions of the offspring from a PP X Pp cross is expected to be homozygous dominant, homozygous recessive, and heterozygous?

• A

  50% homozygous dominant, 0% homozygous recessive, 50% heterozygous

• B

  25% homozygous dominant, 25% homozygous recessive, 50% heterozygous

• C

  0% homozygous dominant, 25% homozygous recessive, 75% heterozygous

• D

  75% homozygous dominant, 25% homozygous recessive, 0% heterozygous
