In given genetic basis of human blood group table find out which belongs to blood group A, B, AB and O [table] S.no. | Allele from Parent 1 | Allele from Parent 2 | Genotype of Offsprings ; I. | $I^{A}$ | $I^{A}$ | $I^{A}I^{A}$ ; II. | $I^{A}$ | $I^{B}$ | $I^{A}I^{B}$ ; III. | $I^{A}$ | i | $I^{A}$ i ; IV. | $I^{B}$ | $I^{A}$ | $I^{A}I^{B}$ ; V. | $I^{B}$ | $I^{B}$ | $I^{B}I^{B}$ ; VI. | $I^{B}$ | i | $I^{B}$ i ; VII. | i | i | i i [/table] [table] A | B | AB | O [/table]
A) [table] I,III | V,VI | II,IV | VII [/table]
B) [table] I,IV | VI,II | II,III | V [/table]
C) [table] VII | II,IV | V,VI | I,III [/table]
D) [table] I,III | II,IV | V,VI | VII [/table]
Explanation
[table] Allele from Parent 1 | Allele from Parent 2 | Genotype of Offspring | Blood Types of Offspring ; $I^{A}$ | $I^{A}$ | $I^{A}I^{A}$ | A ; $I^{A}$ | $I^{B}$ | $I^{A}I^{B}$ | AB ; $I^{A}$ | i | $I^{B}$i | A ; $I^{B}$ | $I^{A}$ | $I^{A}I^{A}$ | AB ; $I^{B}$ | $I^{B}$ | $I^{B}I^{B}$ | B ; $I^{B}$ | i | $I^{B}$i | B ; i | i | ii | O [/table]
