Genetics affects every aspect of life on earth. As a science, it’s one of the

fastest growing fields because it has untold potential — for good and for

ill. Although complicated and diverse, all genetics comes down to basic principles

of heredity and how DNA is put together. So it turns out that genetics,

in many ways, is surprisingly accessible. Genetics is a bit like taking a peek

behind a movie’s special effects to find a deceptively simple and elegant

system running the whole show.
