Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele (r) and
the yellow allele (Y) is dominant to the green allele (y).
The table below shows the F1 progeny that result from selfing four different parent pea plants.

Use the phenotypes of the F1 progeny to deduce the genotype and phenotype of each parent plant.
Complete the table by dragging the correct label to the appropriate location. Labels can be used once, more than once, or not at all.

Plant 1:

Genotype-- Rryy

Phenotype-- round green



Plant 2:

Genotype-- RrYy

Phenotype-- round yellow



Plant 3:

Genotype-- RRYy

Phenytype-- round yellow



Plant 4:

Genotype-- rryy

Phenotype-- green wrinkled
