Homeotic genes control development of whole body segments or structures. When they are overactive or missing, weird things can happen!

Within every cell in our body, two copies of a tumor suppressor gene called BRCA1 are tasked with regulating the speed at which cells divide. This learning module explains how these genes can sometimes mutate, making those cells less...

Try these five self-checking multiple choice questions over gene regulation and mutation.

Mutation is a process that changes a DNA sequence. But how does a difference in a gene's DNA sequence (or genotype) lead to a difference in an observable trait (or phenotype)?

A complete, student-paced lesson on genetics and inheritance. Students work their way through illustrations and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end of the lesson.
