Question

Activity 1: "PEA-ce of Cake"

OBJECTIVE: Identify the genotypic and phenotypic ratios of offspring in the standard monohybrid cross.

Parent 1: _______________
Garden pea plant with homozygous gene pair for round seed
Garden pea plant with homozygous gene pair for wrinkled seed

Genotype (Parent 1): _______________
RR
rr

Parent 2: _______________
Garden pea plant with homozygous gene pair for round seed
Garden pea plant with heterozygous gene pair for round seed

Genotype (Parent 2): _______________
RR
Rr

Answer 1

The genotype and phenotype ratio for the first cross will be 100% Rr and 100% round seeded while that of the second cross will be 1RR:1Rr and 50/50 round/wrinkle seeded offspring respectively.

Genotype and phenotype ratio

For the first cross:

                         RR   x   rr

                      Rr   Rr   Rr   Rr

Genotype ratio: 100% Rr

Phenotype ratio - 100% round seeded

For the second cross:

                        RR    x    Rr

                      RR   Rr   RR   Rr

Genotype ratio: 1RR:1Rr

Phenotype ratio = 50% round seeded and 50% wrinkle seeded.
