उत्तर

The phenotypic ratio of incomplete dominance is 1 : 2 : 1.

Explanation:

In incomplete dominance, both alleles are expressed partially and one gene does not suppress the expression of the other gene. As a result, the two heterozygotes are similar phenotypically and genotypically; hence, the genotypic and phenotypic ratio observed in the F2 generation is 1 : 2 : 1.
