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:
b. fathers genotype:
c. babys genotype:
d. fill in the punnett square below that shows the babys genotype as a possibility.
e. was the baby switched?

Explanation:

Step1: Determine mother's genotype

Blood type A can have genotypes \(I^{A}I^{A}\) or \(I^{A}i\).

Step2: Determine father's genotype

Blood type B can have genotypes \(I^{B}I^{B}\) or \(I^{B}i\).

Step3: Determine baby's genotype

Blood type AB has genotype \(I^{A}I^{B}\).

Step4: Create Punnett square

Let's assume mother is \(I^{A}i\) and father is \(I^{B}i\).

	\(I^{A}\)	\(i\)
\(i\)	\(I^{A}i\)	\(ii\)

Step5: Check if baby could be theirs

Since \(I^{A}I^{B}\) (AB blood type) is present in the Punnett square when mother is \(I^{A}i\) and father is \(I^{B}i\), the baby could be theirs.

Answer:

a. \(I^{A}I^{A}\) or \(I^{A}i\)
b. \(I^{B}I^{B}\) or \(I^{B}i\)
c. \(I^{A}I^{B}\)
d. (See Punnett square above)
e. No
