To solve the problem of determining the expected offspring phenotype ratio from a cross between a heterozygous pea plant for seed coat color, we can follow these steps: ### Step 1: Identify the Alleles The gene for seed coat color in peas has two alleles: - Dominant allele (Y) for yellow seed coat. - Recessive allele (y) for green seed coat. ### Step 2: Determine the Genotype of the Parent ...
