Science Friday
Colorful Chromosomes
Everything is in the genes. Individuals observe 14 different traits of themselves. Using pipe cleaners and beads, the learners create models of a chromosome representing their traits. The class then compares and contrasts everyone's...

Dna From the Beginning: Some Genes Are Dominant
Learn about the principle of dominance as you watch animations showing Mendel's experiments with pea plants. Find out what happened when he crossed plants that produced green seeds with those that produced yellow seeds.
Science Buddies
Science Buddies: Project Ideas: Rad Radishes: Irradiation on Seed Germination
In this plant biology science fair project, students will investigate effects of irradiation on seed germination. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed...

Upper level discussion of several of Mendel's experiments and laws.
OpenStax
Open Stax: Anatomy & Physiology: Patterns of Inheritance
Students learn about patterns of inheritance including genotype and phenotype, and then learn about the inheritance of autosomal dominant and recessive and sex-linked genetic disorders.

Scitable: Gene Inheritance and Transmission
Get an in-depth look at gene inheritance and transmission with this webpage. This site explores genetics beyond Mendel and his peas. Investigate transmission genetics with the following topics gene linkage, variation in gene expression,...
Concord Consortium
Concord Consortium: Stem Resources: Meiosis
Why don't you look exactly like your brother or sister? Meiosis involves the reducing of genetic material and chromosome shuffling which results in different genetic combinations. In this activity, students will view a computer model of...
Concord Consortium
Concord Consortium: Stem Resources: Modern Genetics
Try your hand at mating dragons to learn about genetic recombination, meiosis, and inherited traits. Understand how chromosomes separate in meiosis with a science animation. Then change alleles for the dragons to see what happens to...
City University of New York
Brooklyn College: Genotype and Phenotype
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...
Biology Corner
Biology Corner: Pipe Cleaner Babies
Using chromosome and gene models, students play the roles of two parents in this genetics simulation. The object is to create four offspring and determine their genotypes and phenotypes, and determine the probability of having offspring...
Concord Consortium
Concord Consortium: Geniverse Software
A collection of virtual labs focusing on genetic activities relating to a made up dragon genome. Students explore how inheritance works by studying different cases and running breeding experiments. By changing alleles, students perform...

University of Arizona: Monohybrid Problem Set
This site, which is provided for by the University of Arizona, gives problems online that correspond to basic Mendelian genetics. Test your knowledge once you've read about Mendel and accessed the links to the various subjects covered in...
University of Arizona
University of Arizona: Dihybrid Problem Set
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.
