Which of the following characteristics represent ‘Inheritance of blood groups’ in humans?

Options

(a) Dominance,Co-dominance,Multiple allele.
(b) Co-dominance,Incomplete dominance,Polygenic inheritance
(c) Multiple allele,Polygenic inheritance,Dominance
(d) Incomplete dominance,Co-dominance,Polygenic inheritance

Correct Answer:

Dominance,Co-dominance,Multiple allele.

Explanation:

Inheritance in human blood group shows multiple alleles, dominance as well as codominance.a. The Rh(D) group is also dominant and will be expressed if inherited from either parent. b  Within the ABO Blood Group system, the A and B genes are co-dominant, i.e. these will be expressed whenever the gene is present. The O gene is silent and only expressed when neither A nor B is present. c. Three alleles are responsible for the different types of blood groups in humans which shows multiple allelism.
