Which statements correctly describe the inheritance pattern for the alleles that control blood type?

check all that apply.

1. ia is dominant.

2. ib is dominant.

3. i is dominant.

4. ia is recessive.

5. ib is recessive.

6. i is recessive.

Statements 1,2 and 6 are correct statements.

Explanation: Blood group is determined by three alleles IA, IB and i. IA and IB are dominant alleles and show phenotype blood group A and blood group B respectively when they're combined with allele i. But when IA is combined with IB the phenotype of the blood group is AB and when allele i is combined with another allele I, no antigen is present in the phenotype of blood group and it is labelled as blood group O. It shows IA and IB both express themselves so they're dominant while allele i doesn't express itself so it is a recessive allele.

The correct answer is 1,2, and 6. I took the test trust me.
