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.

Instructional module focusing on Gregor Mendel's Laws of Inheritance. Discussion includes Mendel's discovery of dominant and recessive traits as well as co-dominance and incomplete dominance in genetics. Site also includes an interactive...

Discover how Gregor Mendel uncovered the key principles of inheritance using a simple, familiar system: the pea plant. Learn about Mendel's life, his experiments, and his legacy.

Explore the connection of genes and enzymes in regards to heredity and genetics. Concepts associated with dominant and recessive traits are also presented.

This personal site gives the seven characteristics that Mendel observed and a fairly large background to what Mendel saw and interpreted.

Resource provides a discussion of Mendel's law of segregation with a focus on genotype, phenotype, alleles, heterozygous/homozygous, and 2 x 2 Punnett squares.

This site is a summary of a lecture given at the University of Washington about Mendel's Experiments concerning the 3:1 segregation ratio.

Article defines Mendel's law of independent assortment, provides examples, and takes a look at how it is used to make predictions. Also, discusses dihybrid crosses and 4 x 4 Punnett squares.

This interactive activity, adapted from the Dolan DNA Learning Center, illustrates how Gregor Mendel used purebred yellow and green peas to show that some genes are dominant and others are recessive.

Historical perspective on Mendel's contribution. Spends a little time setting up what the current beliefs of Mendel's day were and how he changed things with what he did.

This provides access to a webbook about How Humans Evolved. The following topics are covered: (1) How Evolution Works, (2) Primate Behavior and Ecology, (3) The History of Human Lineage, and (4) Evolution and Modern Humans. Each chapter...

Learn about Thomas Hunt Morgan's experiments with the fruit fly (Drosophila melanogaster) as a model system.
