One example of a gene with four alleles is the ABO blood group gene, which determines human blood types. The gene has three main alleles: A, B, and O, with the A and B alleles being co-dominant and the O allele being recessive. However, the presence of additional alleles, such as those associated with rare subtypes (like Ax or Ay), can extend the total number of recognized alleles for this gene. This genetic variability contributes to the diversity of blood types in the population.

Alleles
No, all alleles at a specific gene locus are not identical. Alleles are different forms of a gene that can result in different traits or characteristics. Each individual inherits two alleles for each gene, one from each parent. These alleles may be the same (homozygous) or different (heterozygous).
Different versions of the same gene are called

Alleles are alternate forms of the same gene. A gene is the basic physical unit of heredity that is passed on from a parent to their children.
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
the alternative form of a gene is called an "allele."
Alleles
Gene flow
The two different molecular forms of a gene are called alleles.
The alleles are the different forms of the gene. This is simplified, but an example might be, if the gene is "eye color," the alleles would be "green, blue, brown, etc." The variations in the gene are the alleles.
That depends on the gene: some genes have only a few alleles, some genes have hundreds or even thousands of alleles.
Alleles
A different version of the same gene is called an allele. Alleles are variations in the DNA sequence of a gene that can result in different traits or characteristics. Individuals inherit two alleles for each gene, one from each parent.
