Which of the following characteristics represent' Inheritance of blood

1.	Which of the following characteristics represent' Inheritance of blood groups' in humans ?a. Dominanceb. Co-dominancec. Multiple dominanced. Incomplete dominancee. Polygenic inheritance(1) b, c and e (2) a, b and c(3) b, d and e (4) a, c and e
Answer» Correct option (2) a, b and c Explanation Dominance, codominance and multiple alleles are the characteristics that represent 'inheritance of blood groups' in humans. ABO blood groups are determined by the gene I. There are multiple (three) alleles; I^A, I^B and I⁰ of this gene. Allele I^A and I^B are dominant over I⁰. However, when I^A and I^B aIIeles are present together, they show codominance. Therefore, option (2) is correct.

Answer»

Correct option (2) a, b and c

Explanation

Dominance, codominance and multiple alleles are the characteristics that represent 'inheritance of blood groups' in humans. ABO blood groups are determined by the gene I. There are multiple (three) alleles; I^A, I^B and I⁰ of this gene. Allele I^A and I^B are dominant over I⁰. However, when I^A and I^B aIIeles are present together, they show codominance.
