Children often look like their parents. They have their father's nose and their mother's eyes. Why is that?
Some animals have very strange colors and characteristics. How did they come to be that way?
Humans and other organisms look and act the way they do because of the traits they inherit from their parents and the influences of the environment. "Nature versus Nurture" is an age old argument. These websites explore heredity and the role environment plays in shaping the way organisms look and act.

    •An Inventory of My Traits
Students take an inventory of their own easily-observable genetic traits and compare those inventories with other students in groups.
    •Comparing Inherited Human Traits
This activity and reference includes photographs of several inherited human traits that are due to one or more genes.
    •Traits Bingo
In this bingo game students cross off or color bingo squares in response to questions about their traits.
    •How to Extract DNA From Anything Living
A fun activity to extract DNA strands from common foods using simple techniques.
    •DNA From the Beginning
This is an extemely useful website to explain the basics of DNA and its role in heredity. There are brief concept summaries, animations, images, audio and video, problems and other useful links. This resource progresses from simple explanations into quite a bit of detail.
    •Genetic Science Learning Center
In addition to explaining the basics of DNA, this website also explores genetic disorders. There are also some very interesting hands-on activities.
    •Life Emerges on your world
A very intersting page that gives a nice overall picture of cell functions and chromosomes.
    •A Cartoon Guide to Genetics
A scrolling cartoon does a wonderful job of providing a "big picture" view of the role of DNA and genetics in our lives.
Natural Selection
