Answer 1

Answer:

b) 1:2:1

In four o'clock plants (Mirabilis jalapa) we can Gross a plant with red flower petales with another with white petales, the offspring have pink flower petales. If these pink flowered F1 plants are crossed, the F2 plants appear in a ratio of 1:2:1, having red, pink or white petals, respectively.
