In garden peas, Mendel discovered that tall plants (T) are dominant to dwarf (t), yellow seed color (Y) is dominant to green 
, and round (R) is dominant to wrinkled (r). What would the phenotypic rations of the offspring be from a cross between two plants, TtyyRr x ttYyRr? do the gametes first, then Punnett square to get the genotypic ratios, then figure out what the phenotypes will be and finally give the phenotypic tatios.
