Solution
The correct option is B Incomplete dominance
In incomplete dominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype that is a blending of the parental traits.
Consider an example of red flower and white flower. When they are cross-bred, in F1 generation all the flowers will be pink (R1 R2). When F1 generation is self-pollinated, we get one red (R1 R1) flower, two pink (R1 R2) flowers and one white (R2 R2) flower. So the ratio for incomplete dominance is 1:2:1 for both, genotype as well phenotype in F2 generation.Thus, the correct answer is 'Incomplete dominance'.
