Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
Blood type is determined by the presence of specific alleles for the ABO blood group system. There are three main alleles: A, B, and O. The A and B alleles are co-dominant, meaning that if both are present (genotype AB), both antigens are expressed on the red blood cells. The O allele is recessive, so an individual must have two O alleles (genotype OO) to express the O blood type.

The type of interaction between alleles where both alleles are expressed in the phenotype is known as codominance. In codominance, neither allele is dominant or recessive, resulting in a phenotype that displays characteristics of both alleles simultaneously. A classic example of this is seen in the ABO blood group system, where individuals with genotype AB express both A and B antigens on the surface of their 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 genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.

A Phenotype, physical appearance.
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.

Yes, a combination of alleles that an individual has for a particular gene is known as their genotype. This genetic code determines the traits and characteristics of an individual, based on the expression of those alleles.
In genetics, homozygous genes are identical alleles, while heterozygous genes have different alleles. For example, TT(same alleles) is homozygous genotype, while Tt (different alleles) is a heterozygous genotype.
