Is a person's sexual orientation determined at birth? With the informative website, scholars prepare for a debate about the topic. They learn the top pro and con arguments and read through a historical timeline of homosexuality. They...

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...

Do you know the difference between population genetics and quantitative genetics? This webpage examines both population genetics which concentrates on frequencies of alleles and genotypes and quantitative genetics which deals with the...

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...

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

In this informative site, you will find the definition of genotype and phenotype, an explanation of the relationship between genotype and phenotype, an example of a genetic trait, an explanation of the flow of information from DNA to...

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

The basic principles of genetics are in this effective site. Gender determination, recessive traits, and the Punnet Square are the topics examined. There is also a Punnet Square practice exercise to assess your comprehension of the...

A good site to establish what is meant by gene linkage and sex-linkage.

Article reviews Mendel's basic model of inheritance then provides an overview of variations on Mendel's laws, including multiple alleles, incomplete dominance, co-dominance, pleiotropy, lethal alleles, sex linkage, genetic interactions,...

Explains and gives examples of polygenic inheritance.

Find out how epigenetic tags that tell genes whether to turn on or off in their lifetime, act as a cellular memory.

Explains basic genetics concepts, including genes, DNA, chromosomes, sex chromosomes, how traits are inherited, genetic variation, cloning, and stem cells.

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

A useful introduction from the Oak Ridge National Laboratory on the study of how genetics and behavior are linked. Many useful resource links are included.

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

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

Read about the PTC gene, and listen to scientists discuss this accidental discovery which lead to important clues about human evolution.

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.

Read this short article to find out about the history of cloning and genetic engineering. Continue on to the next page to find out how cloning is done. Simple terms and fun animations make it easy to read.
