In case of incomplete dominance in the f2 generation_______________________?
Correct answer: A. Phenotypic ratio corresponds to the genotypic ratio
- A. Phenotypic ratio corresponds to the genotypic ratio
- B. Ratio of genotypes is 3:1
- C. Ratio of phenotypes is 3:1
- D. None of the above
Explanation
With incomplete dominance, the heterozygote has its own intermediate phenotype, so the three F2 genotypes produce three phenotypes in the same 1:2:1 proportion. Thus, phenotypic and genotypic ratios correspond, unlike the 3:1 phenotypic ratio of complete dominance.
