NEET Zoology Question (2024) — Solution

Question

The mother has A + blood group the father has B + and the child is A +. What can be the possibility of genotypes of all three, respectively? A. I^A I^A |I^B i | I^B i B. I^A I^A |I^B i | I^A i C. I^B i |I^A I^A | I^A I^B D. I^A I^A |I^B I^B | I^A i E. I^A i |I^B i | I^ A_i Choose the correct answer from the option given below:

Options

  1. A. C and D
  2. B. D and A
  3. C. A and B
  4. D. B and E

Answer

D. B and E

Step-by-step solution

The child blood group is ( A ^* ) that means he must have received ( i ) allele from the father i.e. the father genotype is (I^B I ). While mother can have ^ ^ or ^A genotype. So, the possible genotypes of all three i.e. mother, father and child respectively would be either (B) I^A I^A |I^B i | I^A i (E) I^A i |I^B i | I^ A_i
