Question

what are their genotypes and phenotypes for color? these are the parent peas. 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

Step1: Determine Genotype Type

Parent 1 has genotype \( YY \). Since both alleles are the same and dominant (assuming \( Y \) is dominant for yellow), it's homozygous dominant.

Step2: Determine Phenotype

Since \( Y \) is dominant for yellow (common in pea color genetics, yellow is dominant over green), the phenotype is yellow.

Parent 2

Step1: Determine Genotype Type

Parent 2 has genotype \( Yy \). Since the two alleles are different (\( Y \) and \( y \)), it's heterozygous.

Step2: Determine Phenotype

Because \( Y \) is dominant (for yellow), even with a \( y \) allele, the phenotype is yellow (dominant allele expresses the phenotype).

Answer:

• Parent 1:
• Genotype: Homozygous Dominant
• Phenotype: Yellow
• Parent 2:
• Genotype: Heterozygous
• Phenotype: Yellow
