BioLogica

Provides a fun way to learn about genetics. Try these games online "Dragon Genetics" and "Mendel's Peas". You must have the Shockwave plugin to view and interact with these simulations. Downloads are also available.

Cat Color and Fur Length Genetics

This web page covers common cat colors, basic color terminology, and color genetics. Domestic cats exhibit a rich variety of coat patterns and colors. The names given to these colors and patterns are increasingly based on genetic theory.

Cat Colors FAQ: Cat Color Genetics

This FAQ covers common cat colors, basic color terminology, and color genetics.

Drag-and-Drop Genetics

This interactive website lets the student drag and drop symbols to make their own crosses. Includes examples for monohybrid, codominance, sex linkage, and pedigrees.

Gene Interactions 

A thorough investigation of gene interactions. Includes: characteristics of x-linked traits, codominant alleles, incomplete dominance, multiple alleles, epistasis, polygenic inheritance, pleiotropy, plus more.

Mendel's Paper (English - Annotated)

Experiments in Plant Hybridization (1865) by Gregor Mendel, read at the meetings of February 8th, and March 8th, 1865.

MendelWeb Homework Sets

MendelWeb is an educational resource for teachers and students interested in the origins of classical genetics, introductory data analysis, plant science, the history and literature of science. 

Online Mendelian Inheritance in Man 

Online Mendelian Inheritance in Man is a database catalog of human genes and genetic disorders, containing textual information, pictures, and reference information. 

Patterns of Inheritance 

This site looks at the single abnormal gene (autosomal dominant/recessive, x-linked dominant/recessive inheritance), chromosomal abnormalities, and genetic counseling. 

The Biology Project: Mendelian Genetics

Part of the Biology Project website, this section provides problem sets and tutorials on monohybrid, dihybrid crosses and sex-linkage.

The Interactive Fly 

A cyberspace guide to Drosophila genes and their roles in development. 

 

Aneuploidy 

This web page discusses aneuploidy. All organisms, tissues or cells that contain n chromosomes or a multiple of it are termed euploid in contrast to sets that have either an additional chromosome or lack one. These are called aneuploid.

Aneuploidy and Deletions 

Aneuploidy and Deletions explains the terms of Euploidy and Aneuploidy, and discusses the occurrence of chromosomal deletion.

Blazing a Genetic Trail 

Is a site hosted by the Howard Hughes Medical Institute that carries out research on human mutations. Families and scientists join in seeking the flawed genes that cause disease.

Cystic Fibrosis 

The various websites listed below looks at the nature of the disease, symptoms and management of the disease.

• Cystic Fibrosis
• Advances in Cystic Fibrosis
• The Genetics of Cystic Fibrosis
• Mutations causing Cystic Fibrosis

Fragile X Syndrome 

Maintained by the National Fragile X Foundation, learn more about Fragile X Syndrome. What is it, symptoms and treatments of this inherited genetic condition.

Mutant Fruit Flies 

The fruit flies (Drosophila melanogaster) in this exhibit show just a few of the mutations that occur in natural fruit fly populations. This interactive site allows you to click on thumbnail size images to see how each fly's phenotype has been altered. 

Genetic Mutations 

Part of Biology Online's genetics section, this page introduces non-disjunction and Down's Syndrome and illustrates how genetic mutations occur.

Mutations
