Relationships between alleles of the ABO blood group system can be explained by:
Correct answer: A. Complete dominance and Co dominance
- A. Complete dominance and Co dominance
- B. Incomplete dominance and Codominance
- C. Over dominance and Incomplete dominance
- D. Complete dominance only

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.
