help making a punnet square

timer Asked: Dec 29th, 2012

Question Description

"Consider a cross between a pea plant that is heterozygous for round seeds and a pea plant that has wrinkled seeds. The allele for round seeds (R) is dominant over that for wrinkled seeds (r). Using a Punnett square, determine the genotypes of the offspring."

Okay so this is what i have so far below

Let R represent the dominant allele (rounded seeds). Let r represent the recessive allele (wrinkled seeds).

Parents- Round seeds (Rr) x Wrinkled seeds (rr)



My problem is the question doesn't say whether the wrinkled seeds plant is heterozygous, so am i right here in assuming it is homozygous?
