You always have 2 copies of each gene (except the sex chromosomes for men) but they can be of different forms. For example to have brown eyes you only need one copy of the brown eye gene to have brown eyes--BB or Bb. You get 1 from you mom and 1 from your father--so you have 2 alleles(copies) of all your genes.

> > - Pleiotropic? This just means "of many forms" For example some bacteria are pleiotrophic, they come in all shapes--no specific shape is standard.

A good place to get info is to use the search engine Google under the advanced search option. www.google.com Just type in the word or phrase you're looking for, you can even specify Dutch--if you wish.
