Which trait in human in an example of multiple alleles?
Correct answer: C. ABO-Blood Group
- A. Eye Colour
- B. Skin Colour
- C. ABO-Blood Group
- D. Rh-Blood Group
Explanation
The human ABO blood type is a good example of multiple alleles. Humans can have red blood cells that are of type A (IA), type B (IB), or type O (i). These three different alleles can be combined in different ways following Mendel's Laws of Inheritance.

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.
