High schoolers examine the structure and functions of DNA. They discover the effects radon has on one's DNA and how it leads to cancer. They discuss why DNA is so important to us.

Young scholars observe the embryological development in the zebrafish. Developmental hierarchy from three germ layers is studied in depth. Research is validated on the body plan of the embryo.

Students complete experiments on antibiotics and antimicrobials. In groups, they explain how antibiotics affect the evolution of microorganisms. They test various types of bacteria to discover how much resistance they have to antibiotics.

High schoolers examine the roles in which animals play in the pollination of plants. They recognize that flowers have male and female sexes. Students describe cross pollination and propose reasons for cross pollination through narration...

What causes a genetic mutation? What is the effect of these mutations? Learn about genetics mutations in this tutorial.

Discusses common mutations that occur in the human population and describes the many different types of genetic mutations and their impact.

Students define and describe mutation including the common causes of mutation.

Learn how genetic disorders are passed from parents to children as explained in this excerpt from Blazing a Genetic Trail, from the Howard Hughes Medical Institute.

In Blazing a Genetic Trail, by the Howard Hughes Medical Institute, follow this three-step approach to treating genetic diseases.

Questions related to processes of cell division, differentiation, and specialization.

For this lab activity from Shelly's Science Spot, students investigate how genetic mutations can affect the ability of animals to survive, by helping, harming, or having no impact.

Only a few types of aneuploidy are compatible with life. Use this drop-down menu to understand more about common genetic disorders resulting from monoploidy and polyploidy, such as Down Syndrome. Learn features of the disorder, see how...

Explains what genetic diversity is, things that cause it, factors that affect it negatively, and why it is so important. Includes examples of the presence and absence of genetic diversity.

Get a brief overview of the connection between mutations and genetic diseases. Several causes of mutations are also presented.

Find out how tiny variations in DNA can help scientists predict humans' response to drugs or to disease risk.

Practice questions over genetic mutations- Passage 1.

This site explains genetic beliefs before and after Mendel, and also includes a section on Mendel himself and his experiments, entitled, "The Monk and his Peas".

A collection of articles on evolutionary genetics focusing on the topics of phylogenetics, mutation and molecular population genetics, the genetics of speciation, genome evolution, and evolution and development. Learn how to read a...

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)?
