A homozygous round seeded plant is crossed with a homozygous wrinkled seeded plant. what are the gentypes of the parents?
Are you concerned about the genotypes of parents or offspring?
R = round, W = wrinkled
If one parent was RR (homozygous)and the other was WW (homozygous), all the offsprint would be RW. All one parent can give is R, and all that the other parent can give is W.
