Genome size is the total number of base pairs in an organism. While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always proportional to genome size (blue bars, in millions of base pairs). Note how many genes a fruit fly can squeeze out of its relatively small genome.

Scientists are intrigued by genetic variation among their own kind: human beings. As scientists make advances in the techniques of genomics — the use of modern analytical tools like computers to process large amounts of genetic information — they are increasingly able to ask broader questions, analyze larger samples, and draw more salient conclusions about how genetic variation in human populations has operated over the past 200,000 years. In this page, you will learn about some of the ways in which genomic techniques have been applied to the study of the human species.
