ABO locus is on chromosome number:
Correct answer: B. 9
- A. 19
- B. 9
- C. 11
- D. 21
Explanation
The ABO blood group locus is located on chromosome number 9. This locus determines the ABO blood group system, which classifies human blood into four main types: A, B, AB, and O. The ABO blood group system is based on the presence or absence of specific antigens (A and B antigens) on the surface of red blood cells.

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.
