No, autosomal recessive
Human blood type is determined by codominant alleles.
codominant alleles
2
In the ABO blood group system, the alleles A and B are codominant, meaning that when both are present, they are expressed equally. In contrast, the O allele is recessive to both A and B alleles. Therefore, when A or B is present with O, only the A or B phenotype is expressed, making O the non-codominant allele in this system.
Yes, codominant alleles assort independently during Mendelian inheritance. This means that the inheritance of one pair of alleles does not influence the inheritance of another pair of alleles on different chromosomes. Each allele segregates independently into gametes during meiosis.

Codominance is a genetic phenomenon where two different alleles for a trait are expressed equally in the phenotype of an organism. An example of codominant alleles is the ABO blood group system, specifically the A and B alleles. When an individual inherits both the A and B alleles, their blood type is AB, displaying characteristics of both types without blending, which illustrates that neither allele is dominant or recessive. This results in both A and B antigens being present on the surface of red blood cells.
Which statement describes the blood type of a person with the alleles IAi? It is type AB because I and i are codominant. It is type AB because A and i are codominant. It is type A because i is dominant and A is recessive. It is type A because A is dominant and i is recessive.

The prefix "co-" in codominant signifies a relationship where two alleles of a gene are both fully expressed, without one being dominant over the other. In genetics, codominance occurs when both alleles in a heterozygous individual contribute equally to the phenotype.
The allele for the sickle cell trait is codominant with the normal allele. This means that in individuals with both alleles present, both traits are expressed.
Dominant markers show only the dominant allele and mask the recessive allele, while codominant markers show both alleles separately. With dominant markers, heterozygotes can't be distinguished from homozygous dominant individuals, while with codominant markers, heterozygotes display a distinct phenotype from homozygous individuals. Dominant markers are easier to interpret but may not provide as much information as codominant markers.
