Question

Finally, look at the Punnett square again and write the numbers of offspring with each phenotype.

Answer 1

We have a dihybrid cross, that is to say, we are working with two alleles, color, and seed type, R for round seeds, r for wrinkled, P for purple, and p for white.

The genotype proportions represented in the image are

PPRr: 4-----Purple, round

PPRR: 2-----Purple, round

PPrr: 2------ Purple, wrinkled

ppRr: 4----- White, round

ppRR: 2----- White, round

pprr: 2-------White, wrinkled

Therefore the phenotypic frequencies are

Purple flowers, round seeds: 4+2= 6

Purple flowers, wrinkled seeds: 2

White flowers, round seeds: 4+2=6

White flowers, wrinkled seeds: 2
