People Are Like Peas in a Pod

Explore single-gene traits in humans. After viewing a video introducing genetic vocabulary, individuals identify their phenotype and possible genotypes of specific traits. They consider both dominant and recessive traits. This is the...

A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...

Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They...

Finally, here is a genetics worksheet that does not include Punnett squares! Designed for a more advanced class, biology learners will compare Lamarck's concept of evolution with Darwin's. They will explore the Hardy-Weinberg equilibrium...

Population genetics deals with genetic differences within and between populations. The video explains why this is the lowest level of evolution. Then it discusses mutations, environmental factors, genetic recombination, and random gamete...

Learners explore population genetics, or how populations of species change over time, leading to evolution with a video that brings together the principles of Mendel and Darwin and explains and models the Hardy-Weinberg equation.

Show learners how to apply genotypes of parents to a Punnett square to determine potential genotypes and phenotypes of offspring with a video that explores monohybrid crosses and then complete a dihybrid cross as well. 

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

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...

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...
