Question
Which of the following is the genotype for blood group B?
- Both b and c
Hint:
IB should be present as at least one of the allele for a person with B blood group.
The correct answer is: Both b and c
- Blood group is a physical trait that is due to the expression of the alleles of a gene.
- In a specific gene, two alleles are present.
- The two alleles can be of same or different types.
- In blood group, IA and IB are dominant alleles while i is a recessive alleles.
- For B blood group, at least one allele should be IB
- Hence, the genotype of an individual can be either IBIB or IBIO
- Dominant allele will mask the effect of the recessive allele.
