Question

these are the parent peas. what are their genotypes and phenotypes for color? parent 1 yy genotype: homozygous dominant homozygous recessive heterozygous phenotype: yellow green parent 2 yy genotype: homozygous dominant homozygous recessive heterozygous phenotype: yellow green

Explanation:

Parent 1:

• Genotype: A homozygous dominant genotype has two dominant alleles. Parent 1 has genotype \( YY \), so it is homozygous dominant.
• Phenotype: The dominant allele for pea color (usually \( Y \)) results in yellow color. Since Parent 1 has \( YY \), its phenotype is yellow.

Parent 2:

• Genotype: A homozygous recessive genotype has two recessive alleles. Parent 2 has genotype \( yy \), so it is homozygous recessive.
• Phenotype: The recessive allele for pea color ( \( y \)) results in green color when present in a homozygous state (\( yy \)). So Parent 2's phenotype is green.

Answer:

• Parent 1:

Genotype: Homozygous Dominant
Phenotype: Yellow

• Parent 2:

Genotype: Homozygous Recessive
Phenotype: Green
