Getting into Your Genes Very Basic Genetics

In This Chapter

^ Defining genes and genomes ^ Decoding the genetic code ^ Going from genotype to phenotype ^ Finding out about mutations

The study of genetics is pretty fascinating, and the language of genetics is cropping up in a growing number of places. It's often in the news and even makes periodic appearances in movies and TV shows. You've probably heard references to DNA and genes; perhaps you've even heard of the Human Genome Project or of specific genes for human diseases. All this aside, you may be wondering why I've included a chapter on genetics in a book about evolution. The answer is simple. Evolution involves genetic changes over time, so to understand evolution, you need to know a little bit about genetics: what it is, how it works, and what parts are particularly important to the study of evolution.
