Question

A baby with blood group AB I born into a family where the mother has blood group type B and the father has type O
Determine whether the husband is the biological father of the baby

Answer 1

The baby AB received the IB allele from the mother and the IA allele from another person. The husband is not the biological father of the baby.

What are the blood type alleles?

Blood type is coded by a triallelic gene

• IA allele is dominant over the i allele
• IB is dominant over the i allele
• IA and IB are codominant
• i is the recessive allele

The genotypes and phenotypes are

• IAIA and IAi → Type A
• IBIB and IBi → Type B
• IAIB → Type AB
• ii → Type 0

In the exposed example,

• Baby → AB → IAIB
• Mother → B → IBIB or IBi
• Husband → 0 → ii

The baby carries one IA allele and one IB allele.

• The IB allele was inherited from the mother.

• The husband could only transmit a recessive allele i. But the baby does not carry any recessive allele.

The baby received the IB allele from the mother and the IA allele from another person.

The husband is not the biological father of the baby.
