Alleles are different forms of a gene. For example different alleles that code for different colors of a plant(yellow or green) or for different traits.(curly hair or straight hair)

DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins.But the ones that do are called genes.

Alleles are different versions of a certain gene.As an example, the gene that codes for blood type has 3 different alleles, A, B, an O. The genes that code for hair and eye color also have many different alleles.
