How did scientists determine the cause of illness before technology? Science scholars play the role of medical researcher in an engaging guided inquiry activity. Using observations, technical reading, and Punnett squares, learners...

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

A great handout to introduce genetics. Young geneticists will begin to examine which traits are prevalent in their own families, helping them begin to understand the concept of dominant and recessive genes. This is an excellent resource...

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

Explains what dominant and recessive traits are and how they work, and provides a list of single gene traits with the degree of manifestation if they are dominant or recessive. Also discusses co-dominance, incomplete dominance, polygenic...

This website provides an answer to the following question: "What are Gene Mutations?" Many links are provided throughout this short description that access information on related subjects.

This resource explains Mendel's first law (Law of Segregation) in detail. Includes Mendel's original experiments with results and conclusions.

This site explains how to determine the chances of inheriting certain traits from our parents. It gives mathematical examples and exercises.

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".

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.

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

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

Explains two types of genetic cross - a reciprocal cross and a test cross. Examples are described for a monohybrid and a dihybrid test cross and for a reciprocal cross.

This lesson will give examples of disorders that are linked to genes on the X chromosome.
