what is the relationship between genes and alleles? What are alleles anyway man? GEEZ!
A gene isn't always "fixed" but has many forms. These forms are called "alleles". You may have a gene or genes for blue eyes that you inherited from, let us say, your mother. But the form of your gene(s) and your mother gene(s) for blue eyes maybe quite different, despite the fact they both give rise to blue eyes.
