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...

What a fun way to explore Mendelian Genetics! Using a computer connected to the Internet, beginning biologists construct and use Punnett squares of monohybrid crosses to explain how genetic traits are passed to offspring. Other websites...

Approximately 89 percent of humans demonstrate right-hand dominance, 10 percent demonstrate left-hand, and the rest show equal dominance between hands. Scholars design an experiment to determine if the dominant hand holds more volume...

Any pattern of inheritance that does not follow Mendel's laws uses non-Mendelian inheritance. The video explains this type of genetics with many guided practice problems. It covers incomplete dominance, codominance, and sex-linked traits.

Male hyenas are not laughing! The species probably doesn't find it funny that they always hold the lowest status in their packs. An intriguing video lesson explains how this comes about and the negative impact on these animals.

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett squares to determine the possible genotypes...

A handout on genetic inheritance begins with a reading on alleles and how they can result in albinism. Junior geneticists learn to complete Punnett squares and participate in a coin toss simulation of allele pairing. They also learn...

Parts of the cell as well as genetic material begin this presentation.  As the slides continue, there are explanations of the main terms used in genetics.  The structure of genetic material, chromosomes, and replication are summarized....

Taboo, anyone?! A vocabulary review lesson asks learners to give their partners clues to help them guess the target word. The catch? There are words that are taboo. If they use the prohibited words, they don't get credit if partners...

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...

Learners plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Learners...

This PowerPoint jumps right into the details of unusual traits and how they are coded.  The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this...

Although these slides seem full of text, the information is bulleted and clear. There is a list of vocabulary and then two slides to define examples of Mendelian inheritance and rules of probability.  The remaining five slides look at...

Make reviewing evolution, cell division, genetics, cell structure, and scientific method more fun! Science Jeopardy allows teams to choose a category for the question they will address. If you complete the entire game, learners will have...

Students simulate a Punnett square.  In this dominant or recessive lesson, students explore possible outcomes of given situations.  They compare and contrast homozygous dominant and homozygous recessive genes.  Students use graphing...

In this genetics worksheet, students answer 42 questions about meiosis and sexual life cycles, Mendel's Laws of Inheritance, chromosomes and protein synthesis.

In this biology worksheet, students identify and match various classes of species found today. Then they explain why biodiversity exists today on earth and define evolution. Students also describe who a paleontologist is and what they do.

In this biology worksheet, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...

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,...

Really a unit, this resource exposes middle schoolers to genetics at their level. They read interviews and biographies, trace a family tree, play games that simulate inheritance concepts, and more! Teacher's procedures, student...

Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils evaluate whether...

Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches...

What you will find in this collection of slides is a comprehensive introduction to genetics. It is technically three separate slide shows: the first on general genetics concepts, the second on rules of inheritance, and the third on...

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...
