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

i. Dominance
ii. Co-dominance
iii. Multiple alleles
iv. Incomplete dominance
v. Polygenic inheritance

Options

  1. Aii, iv and v
  2. Bi, ii and iii
  3. Cii, iii and v
  4. Di, iii and v

Correct answer

B. i, ii and iii

Step-by-step solution

Dominance -( IAIO, IBIO)- the phenomenon whereby, in an individual containing two allelic forms of a gene, one is expressed to the exclusion of the other.
Codominance -( IAI B)- a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive.
Multiple alleles- IA, IB & IO - 3-different allelic forms of a gene.
