In pea plants, tall is dominant to dward and purple flowers is dominant to white flowers. These two traits are regulated by two independently assorting genes.
You then performed a genetic cross between a dihybrid pea plant (that exhibits tallness and with purple flowers) and a dwarf white flowered plant. The cross resulted in 1000 progeny, of which 250 were tall with purple flowers. What is the expected ratio for the other phenotypic classes?

O 200 Short/white flower
350 Tall/white flower
O 200 Short/purple flower
200 Short/white flower
O 200 Tall/white flower
350 Short/purple flower 350 Short/white flower
O 200 Tall/white flower
200 Short/purple flower 250 Short/white flower
O 250 Tall/white flower
250 Short/purple flower
O none of the choices are correct
