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)ResponsesKamar’s mother must be O because the recessive allele allows for Kamar to get type A from his fatherKamar’s mother must be O because the recessive allele allows for Kamar to get type A from his fatherKamar’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 parentKamar’s mother must be AB because blood type AB is inherited from one parentKamar’s mother must be either AB or B because blood types AB is considered codominant

Answer 1

Kamar's blood type is AB, which means he has both A and B alleles. His father's blood type is heterozygous A, which means his father could have either the genotype AA or AO.

To explain the potential blood types of Kamar's mother:

1. If Kamar's mother has blood type O (genotype OO), then Kamar could only inherit an A from his father (A from the father and O from the mother, leading to blood type A), which does not allow Kamar to have blood type AB.

2. If Kamar's mother has blood type A (genotype AA or AO), there is a possibility that Kamar could inherit the B allele from his mother (if she is AO) to get to blood type AB.

3. If Kamar's mother has blood type B (genotype BB or BO), she could provide the B allele for Kamar resulting in AB blood type.

4. Lastly, if Kamar's mother has blood type AB (genotype AB), Kamar would inherit one allele from each parent, yielding AB.

Based on this information, Kamar can conclude:

Kamar’s mother must be either AB or B because blood types AB is considered codominant.

So, the correct response is:
Kamar’s mother must be either AB or B because blood types AB is considered codominant.
