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
  1. ii, iv and v
  2. i, ii and iii
  3. ii, iii and v
  4. i, iii and v

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.
