First project for Wikipedia 

As of April 2, 2008, edited this page as first project.  Any comments appreciated.  Did the following:
 From previous posts, learned that page direction was for terminology, not necessarily biology. But added more succinct genetic information citation to definition, making the body of the text heavier.  Added short biology section because of this.
 Found more usage of the term "black sheep." Depending on the group culture using the phrase, it was either positive or negative, so further clarified usage by splitting the term into two groupings with citations and examples for each.  I know Baa Baa Black Sheep was removed once.  However, it is an example of the use of the term.  The other examples should be obvious.  If not how do I clarify.
 Did not find a standard template for citation on this page.  Would anyone let me know what the standard for this page is and how it was chosen, and I will go back and change.  Thanks.
