This a great article about cri-du-chat syndrome including diagnosis, symptoms, and genetic inheritance.

Find out what happened when Mendel crossed two hybrid pea plants. The animations do a good job explaining why these crosses produce a 3:1 ratio of traits.

Mutations can cause a permanent change in the DNA of an organism. Over many generations, organisms have adapted through mutation which involves small changes between organisms which may allow that organism to compete better for survival....

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.

Explains basic genetics concepts, including genes, DNA, chromosomes, sex chromosomes, how traits are inherited, genetic variation, cloning, and stem cells.

Students learn about patterns of inheritance including genotype and phenotype, and then learn about the inheritance of autosomal dominant and recessive and sex-linked genetic disorders.

This website offers a clear definition of the science of Genetics, highlighting DNA and genes. There is a neat, easy-to-understand animated tour of the basics and an opportunity to go inside an animated cell. Student can build a DNA...

A three-day unit introduces heredity by helping students identify their own genetic traits and then leading them in an exploration of generational traits and variation. Find printable worksheets, data tables, and graphs, as well as...
