use a punnet square t in your pea plants and calculate the ratio of each genotype and phenotype a homozygous green pea plant (Gg) is croosed with a homozygous yellow pea plant (gg)
Answer (1)
Let’s first clarify the parental genotypes. In pea plants, green is dominant to yellow. The cross given is between a heterozygous green pea (Gg) and a homozygous yellow pea (gg). (Note: A “homozygous green” plant would be GG, so here the green parent is heterozygous.Step 1. Determine the GametesGg (green parent): Can produce gametes with either G or g.gg (yellow parent): Can produce gametes with only g.Step 2. Set Up the Punnett Squarepicture Step 3. Analyze the OffspringGenotypes:2 out of 4 (50%) are Gg.2 out of 4 (50%) are gg.Phenotypes:Gg: Shows green phenotype (because green is dominant).gg: Shows yellow phenotype.Thus, the phenotypic ratio is:1 Green : 1 Yellow (or 50% green and 50% yellow).Final AnswerGenotypic ratio: 1 Gg : 1 ggPhenotypic ratio: 1 Green : 1 Yellow
