Kamar wants to know his mother's blood type. Kamar knows that his blood type is AB and his father’s blood type is heterozygous A. What can Kamar assume about his mother’s blood type?(1 point) Responses Kamar’s mother must be either A or O because blood type AB is considered incomplete dominant. Kamar’s mother must be either A or O because blood type AB is considered incomplete dominant. Kamar’s mother must be AB because blood type AB is inherited from one parent Kamar’s mother must be AB because blood type AB is inherited from one parent Kamar’s mother must be O because the recessive allele allows for Kamar to get type A from his father Kamar’s mother must be O because the recessive allele allows for Kamar to get type A from his father Kamar’s mother must be either AB or B because blood types AB is considered codominant

Answer 1

To determine Kamar's mother's possible blood types, we need to consider the genetics of blood types.

Kamar has blood type AB, which means he has one A allele and one B allele. His father is heterozygous for blood type A, which means he can either have the genotype AA or AO. This means Kamar's father can contribute either an A allele or an O allele.

Since Kamar's blood type is AB, he must have inherited one A allele from his father and one B allele from his mother. Therefore, Kamar's mother must contribute the B allele.

The possible blood types that can provide a B allele are:

• Blood type B (genotype BB or BO)
• Blood type AB (genotype AB)

Blood type O (genotype OO) cannot contribute a B allele, and hence cannot be Kamar's mother's blood type.

Given this information, Kamar can assume that his mother must have either blood type B or blood type AB.

The most appropriate response is therefore: Kamar’s mother must be either AB or B because blood type AB is considered codominant.
