Some flowers show incomplete dominance. If RR = white and R'R' = red, which phenotypic ratio would
be expected in the o spring of two pink flowers?

Answer:

1 red: 2 pink: 1 white

0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).

Phenotypic ratio defined as the relative number of offspring expressing a particular trait or combination of traits, which can be determined by performing a test cross and the frequency of the trait or trait combinations being expressed depending on the genotype of the offspring can be identified.

Phenotypic ratio is expressed as the ratio of different phenotypes present in the progeny of a cross where the ratios are numerical comparisons. For example, if one has three mangoes and two oranges, the ratio of mangoes to oranges will be 3:2.

For above given information, if we cross RR which is white with R'R' which is red, we will get 4RR' offspring which are pink in color. then the ratio will be 0 red: 4 pink: 0 white.

Thus, 0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).
