Learners describe the inheritance patterns other than simple dominance. They are taught how Mendel's principles apply to all organisms. Students review the use of Punnett Squares. They are taught the principles of probability and...

Students explore Punnett squares and illustrate specific genotypic and phenotypic genetic outcomes. After a class discussion, students predict the probability of a specific trait being passed on by using Punnett squares. They reveal the...

Young scholars model traits on genes using colored paper and tongue depressors to represent chromosomes. In this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits,...

Students are allowed to strip away the cell walls of plants cells (using enzymes) and then observe the resulting spherical protoplasts (plant cells minus the cell wall). They see that plants cells indeed have a plasma membrane in...

Pupils explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. Pupils plasma membranes, solutes and organelles.

Examine boundaries between science and ethics as scientists work with genetic testing and discovery.

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.

This site from Palomar College provides a good background on exactly what Mendel did. Vocabulary links throughout make this a very good introduction article for genetics.

This biology game assesses understanding of "crossing over", "independent fertilization", and "random fertilization" in the study of genetics.

Learn about the principle of dominance as you watch animations showing Mendel's experiments with pea plants. Find out what happened when he crossed plants that produced green seeds with those that produced yellow seeds.

There are many ways to learn about Gregor Mendel and his pea experiments. This interactive tutorial requires users to actually plant, grow, and cross different plants to observe their traits. Pedigrees are also used to help show dominant...

This site, which is provided for by the University of Arizona, gives problems online that correspond to basic Mendelian genetics. Test your knowledge once you've read about Mendel and accessed the links to the various subjects covered in...

This site is provided by the University of Arizona and it gives great information on the subject. Good collection of dihybrid crosses which exemplify the issue of independent assortment. Work these once you think you've mastered th concept.

Upper level discussion of several of Mendel's experiments and laws.

Mendel's second law and how he arrived at it through his experiments. Includes vocabulary and examples.
