Q. No.Assertion(A): ABO blood grouping shows the presence of three alleles for gene I.
Reason(R): Humans are diploid and hence carry two alleles for all genes.
Choices for Assertions and reasons:
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
3. (A) is true, but (R) is false.
4. (A) is false, but (R) is true.
Reason(R): Humans are diploid and hence carry two alleles for all genes.
Choices for Assertions and reasons:
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
3. (A) is true, but (R) is false.
4. (A) is false, but (R) is true.

Assertion(A): The unmodified (functioning) allele, which represents the original phenotype is the dominant allele.
Reason(R): The modified allele is generally the recessive allele.
