BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION
342136
In ABO system a person has
1 2 alleles
2 3 alleles
3 No alleles
4 Multiple alleles
Explanation:
The gene (\(I\)) has three alleles \(I\)A, \(I\)B and i. But a person will have only 2 alleles.

Which of the following characteristics represent ‘Inheritance of blood groups’ in humans? A. Dominance B. Co-dominance C. Multiple allele D. Incomplete dominance E. Polygenic inheritance
1 B, D and E
2 A, B and C
3 B, C and E
4 A, C and E
Explanation:
• ABO blood groups are controlled by the gene I. Gene (I ) has three alleles IA, IB and i (Multiple alleles) • IA and IB are completely dominant over i. when IA and i are present only IA expresses and similarly when IB and i are present IB expresses (Dominant – recessive relationship) • When IA and IB are present together they both express their own types of sugars: this is because of co-dominance.

Person having genotype \({I^A}{I^B}\) would show the blood group as AB. This is because of:
1 Pleiotropy
2 Co-dominance
3 Segregation
4 Incomplete dominance
Explanation:
When \({F_1}\) generation resembles both parents, this is called co-dominance. This is often seen in ABOblood grouping. Since both A and B sugars are dominant, hence it results in AB blood group.

Out of the three alleles of gene \(I\), the sugar polymers on the plasma membrane of RBCc is controlled by how many alleles?
1 3
2 1
3 2
4 0
Explanation:
The alleles \({I^A}\) and \({I^B}\) produce a slightly different form of the sugar while allele i does not produce any sugar.
