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...

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...

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...

This is a visually attractive PowerPoint that summarizes the life of Gregor Mendel and the genetic traits that he detailed.  Each slide has clear bullet points and lovely images that are helpful and relevant

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...

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.

Have you ever met twins or biological siblings with different skin colors? It's not unusual and a helpful video explains why. It includes incomplete dominance, codominance, polygentic traits, and Epistasis, and even explains why...

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 set of phenotypes is listed for mice, flowers, blood type, and plants. For each, biology buffs analyze the percentages of phenotypes in the offspring and then identify the genotypes of the parents. This is a different approach to...

Students research an area with at least one dominant geographical feature. Then they display their findings in a realistic 3-dimensional presentation. Students also prepare ancillary material to support their project. Finally, they chart...

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...

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...

Students 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. Students...

What do you get when you cross a purple with a white? Genetics geniuses figure it out with a Punnett square. On this assignment, they must solve crosses for incomplete dominance, codominance, lethal dominance, and sex-linked genes. It is...

In this short space, it would be impossible to describe the breadth of this seven-page genetics worksheet. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of...

If mom is bald, will her babies be bald? Here is a practical presentation that can answer that question. Viewers can take notes on the difference between dominant and recessive genes, mutations, and heritability. A large portion of the...

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...

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....
