Different versions of a gene, of which code for different versions of a characteristic.
If the alleles in a mtching pair are the same, they are called homozygous alleles.
If the alleles in a matching pair are different, they are called heterozygous alleles.
Some alleles are dominant to other forums of a gene and will always be expressed.
Some alleles are recessive to other forms of the gene and will rarely be expressed.
