<reasoning>

Analyze the parental genotypes and phenotypes

Using the Dominant and Recessive and Genotype and Phenotype knowledge points

• Parent 1 (left): Genotype \(Yy\) (yellow pod phenotype, indicating \(Y\) is dominant for yellow).
• Parent 2 (top): Genotype \(yy\) (green pod phenotype, indicating \(y\) is recessive for green).

Determine offspring genotypes and phenotypes

Using the Punnett Square and Genotype and Phenotype knowledge points

• Top-left cell: \(Yy\) (yellow phenotype)
• Top-right cell: \(Yy\) (yellow phenotype)
• Bottom-left cell: \(yy\) (green phenotype)
• Bottom-right cell: \(yy\) (green phenotype)

Calculate the phenotypic ratio

Using the Punnett Square knowledge point

• Yellow pods: \(\frac{2}{4} = 50\%\)
• Green pods: \(\frac{2}{4} = 50\%\)
• Phenotypic ratio: 50% yellow; 50% green.
