Multiple choice

In case of incomplete dominance, the monohybrid ratio of phenotypes in F2 generation is

  2. 3:2:1

  3. 1:2:1

  4. 1:1

C Correct answer
Explanation

In incomplete dominance, the F2 generation phenotypic ratio is 1:2:1, reflecting the genotypic ratio because the heterozygote (the '2' in the ratio) has a distinct intermediate phenotype.
