      The different forms of a gene are called alleles. For example, one person may have blue eyes and another brown eyes. The gene that determines eye colour is different in both people, one has the allele for blue eyes and the other the allele for brown eyes.

      Alleles 🙂 and there can be many different versions of one gene!
