In the garden pea, tall vine (d) is dominant over dwarf (d), green pod (y) is dominant over yellow (y) and round seed (w) is dominant over wrinkled (w). a tall, yellow, round plant is crossed to a dwarf, green, round one. the following ratios occurred in the f1 generation: 3/8 tall, green, round; 3/8 dwarf, green round; 1/8 tall, green, wrinkled; and 1/8 dwarf, green, wrinkled. what is the genotype of the two parental plants?
