Introduction

Genetics is the study of you and how you are related to every living creature on earth.

Genetics:: the scientific study of heredity: how particular qualities or traits are transmitted from parents to offspring.

Genetics can answer questions like:

Why are eyes different colors?
Why can some people roll their tongues?
Why do I look like my grandfather when he was younger?

Scientists have recently completed collecting information about the human genome.

Genome:: all the genetic material in the chromosomes of a particular organism.

They can now study in great detail many things about how we are made. Some hope to find the cures for many diseases. Others are curious about cloning techniques, and one mammal has already been cloned: Dolly the Sheep.

Cloning:: the process of making genetically identical copies.
