The F1 progeny is self-pollinated and the flower colour in F2 is observed. Given the above information what is the expected phenotypic ratio of plants with different flower colours ?

A

All plants with red flowers

B

Red: white in the ratio of `3 : 1`

C

Pink: white in the ratio of `3:1`

D

Red: pink: white in a ratio of `1:2:1`
