Question

Mendel discovered that yellow seed color in pea plants is dominant to green. what offspring genotype probabilities are expected for a cross between a plant that produces yellow seeds (heterozygous genotype) and one that produces green seeds? (this is an autosomal trait).

Answer 1

The probability is Ss×ss = Ss, Ss, ss, ss = 50% heterozygous genotype, 50% homozygous recessive genotype = 50% yellow phenotype, 50% phenotype
