Which of the following is an example of incomplete dominance?
Correct answer: B. Snapdragon flower color
- A. ABO blood group
- B. Snapdragon flower color
- C. Human height
- D. Sickle cell anemia
Explanation
In snapdragon, red × white → pink F1. Here heterozygotes show intermediate phenotype, a hallmark of incomplete dominance.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
