Genetics Homework Set Pea plants. Tall (T) is dominant to dwarf (t); purple flower color (P) is dominant to white (p). Problem 2 . Construct a Punnett Square to calculate the ratios of genotypes and phenotypes for a cross between a pea plant that is heterozygous for both traits with a pea plant that is dwarf and white. Show your work. Phenotypes of parents?
