Dragon Genetics ~ Independent Assortment and Genetic Linkage
Imagine a pair of dragons that produce offspring and determine the percentage of the hatchlings have wings and large antlers. This fantastic activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches them how to use Punnett squares.

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, the peas all have arms, legs, and facial features.

Fancy Fish: Gene Frequency
High school biology learners simulate gene flow within a population of fish. They hold colored fish cards as identification and carry "Good & Plenty®” candies to represent alleles, the recessive homozygous of which is lethal. You will need to construct the fish cards and set obstacles up around the room for fish to swim around.

"Easter" Egg Genetics
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 determine the genotypes and then solve a Punnett square for their cross.

Follow fruit fly genetics with this probability activity. Biology scholars analyze the alleles of Bugsy, Daisy, Dino, and Lulu, considering traits for antennae, wing type, and eye color. They solve Punnett squares to determine the genotypes and phenotypes of their offspring.

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all the difference in survival when the landscape changes drastically.

Introduction to Heredity
Young scientists generally love to learn how certain traits can be explained by a direct combination of alleles from their parents. Here, they are able to examine how a phenotype is often expressed as a result of one allele being recessive and one being dominant.

7.013 Spring 2005 Problem Set 2 - Genetics
Three pedigrees are presented for junior geneticists to interpret. Then, a double strand of DNA is printed for them to analyze. Hypothetical animal crosses are described, from which learners determine the genotypes and phenotypes of the offspring.

Dragon Genetics ~ Understanding Inheritance
Juvenile geneticists will jive with this imaginative investigation of inheritance in dragons. Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by the baby dragon.

Variation in a Species
If there are no extenuating environmental factors to ensure competition in a species, then variation is achieved by random mutation. This resource may be more useful after viewers are introduced to the concepts of alleles and the heredity involved with sexual reproduction.

Mendelian and Non-Mendelian Heredity
Tenth graders discuss their physical features, and why they look the way they do. They listen as the teacher discusses DNA, alleles, and dominant or recessive genes. Students perform an experiment with different colored markers representing alleles to determine genotype and phenotype ratios among offspring.

Introduction to Genetics
For this genetics worksheet, students review vocabulary words associated with genetics including allele, gamete, hybrid, trait, and Punnett Square. This worksheet has 10 matching, 5 fill in the blank, and 10 multiple choice questions.

After learning to calculate probabilities for single examples of genetic crosses in a previous lecture, students are exposed to the concept that allele and genotype frequencies in a population remain in constant equilibrium. A reasonable grasp of math is necessary to comprehend this presentation.

Genetics and the Work of Mendel
Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images are a great recap of all concepts pertaining to this topic.

Again, the basis for trait inheritance and the impact of alleles in phenotypes was covered in previous videos. This presentation focuses on gender and the likelihood of traits if they are sex-linked. Sal tells a great anecdote about where the blame should have been placed for Henry VIII's female offspring.

Genes within Populations
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 principle, compare allele and genotype frequencies, and describe agents of evolutionary change.

Genetics Practice 1: Basic Mendelian Genetics
Six genetics problems are to be solved by junior geneticists. Empty Punnett squares are provided for them to plant the parents' alleles and determine the genotype, phenotype, and frequency of offspring. All of the problems involve actual traits except one: the possession of a horn in purple-people eaters!

Measuring Evolution of Populations
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 characteristics of populations.

Hardy Har Har: Investigating the Hardy-Weinberg Principle
Well, shiver me timbers! Biology pupils practice using the Hardy-Weinberg principle for computing change in gene frequency within a fictional population of pirates. The genetic trait being analyzed is the presence of sea legs, legs that prevent them from falling over when the ship is tossing.
