The ABO blood group is controlled by more than two alleles in a population. This shows that ABO blood group is an example of:
Correct answer: B. Multiple Alleles
- A. Polygenic Inheritance
- B. Multiple Alleles
- C. Operons
- D. Allelic interaction
Explanation
In the ABO blood group system, there are more than two alleles (A, B, and O) that control the blood type in a population. Each individual inherits two alleles from their parents, resulting in a combination of these multiple alleles determining their blood type.

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.
