ACTIVITY: Problem Solving Direction: Solve the problem below using the Punnett square and give both the genotypic and phenotypic ratios. (10 points) • In pea plant, round seeds (R) is dominant over wrinkled seeds (. Yellow colors (Y) are dominant over green color (y). If you cross heterozygous Round, Yellow seed (RrYy) and homozygous Round, Yellow seed (RRYY) what will be the possible phenotype and genotype of the offspring? I NEED RN
