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".

[Free Registration/Login may be required to access all resource tools.] Mendel laid the foundation for modern genetics, but there were still a lot of questions he left unanswered. What exactly are the dominant and recessive factors that...

Learn genetics and inheritance works on a molecular level.

For a concise summary of human blood types, this is a great resource. Discussion includes the topics of genotype, phenotype and agglutinins. There is also a nice pictorial table that summarizes the three blood types.

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.

Middle schoolers will explore Gregor Mendel's laws of genetics in this instructional activity. Students will be paired in male and female groups. If girls and boys can't be evenly divided, same sex middle schoolers can be paired to...

Learn how to find allele frequency and how it's different from genotype frequency.

How natural selection works at the level of genes, alleles, genotypes, & phenotypes.

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

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.

Good description of Mendel's findings and his second major principle.

This resource provides directions for a lab in which young scholars observe changes in a gene pool of bunnies affected by natural selection. Includes PDF resources.
