    Very simply, Het is short for heterozygous. This is the state in which an animal carries both a normal and a mutant gene on a particular chromosome. This is the intermediate state between Normal when two normal genes are present and the mutated form (or Homozygous for the mutated gene) where the animal possesses two copies of the mutant gene on that chromosome.

    And to break it up-and-away from Reptiles - here is a link to a horse that is Homozygous for Pinto and Black genes - so will only produce a coloured foal like himself, will not produce chestnut (dominant recessive gene that is knocked out by homozygous gene) and the only gene that stops his colour being produced is the grey gene.

    Reptiles are a little bit easier to deal with I think. :)
