CanaryCulture Concepts in Genetics

Abstract

In part I of this article we learned the basics of biological mechanics and terminology dealing with reproduction. Also, we learned that the DNA in the genes determines what the canary will look like.

The many variations among animals led scientists to conclude that DNA does not always copy itself exactly. If DNA had always copied itself, the original green canary would still be the only color in existence. A gene is an extremely stable structure. It may remain stable through many generations, copying itself correctly between each cell division. Occasionally, a mistake occurs in the copying process. A change in the gene is called a mutation.
