R is the dominant allele for round pea texture; r is the recessive allele for wrinkled pea texture. If you cross plants having round peas with plants having wrinkled peas, ____.
A) all progeny will be homozygous for pea texture
B) you are conducting a dihybrid cross
C) you are conducting a reciprocal cross
D) all progeny will have wrinkled peas
E) you will be able to determine if the plant with round peas is homozygous or heterozygous for this trait

Crossing a plant with round peas (which could be RR or Rr) with a plant with wrinkled peas (rr) allows you to determine the genotype of the round pea plant based on the phenotypes of the progeny. If any progeny have wrinkled peas, the round pea plant must be heterozygous (Rr).
