Question

1. two other parents think their baby was switched at the hospital. the mother has blood type a, the father has blood type b, and the baby has blood type ab.

a. mothers genotype: __ or __
b. fathers genotype: __ or __
c. babys genotype: ____

Explanation:

For blood type, if the mother has blood type A, her genotype can be \(I^{A}I^{A}\) (homozygous) or \(I^{A}i\) (heterozygous). If the father has blood type B, his genotype can be \(I^{B}I^{B}\) (homozygous) or \(I^{B}i\) (heterozygous). For the baby with blood type AB, its genotype is \(I^{A}I^{B}\) as blood type AB is codominant.

Answer:

a. \(I^{A}I^{A}\), \(I^{A}i\)
b. \(I^{B}I^{B}\), \(I^{B}i\)
c. \(I^{A}I^{B}\)
