Got Lactase? The Co-Evolution of Genes and Culture
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Reebops: A “Model” Organism for Teaching Genetic Concepts
In a sweet simulation, junior geneticists examine the chromosomes of a fictitious Reebop marshmallow animal, combine chromosomes to produce offspring, and then make a model of the resulting Reebop baby. Phenotypes include number of...

How Mendel's Pea Plants Helped Us Understand Genetics
A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation,...
