Geneticists of the future identify heterozygous and homozygous genotypes, describe phenotypes, and use Punnett squares to solve problems and determine characteristics of offspring. A total of 15 questions make this a compact quiz or...

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...

Students create a family pedigree, relate the laws of inheritance to a family pedigree, and determine certain phenotypes and corresponding genotypes of members in their family.

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity worksheet covers the differences in genotypes and...

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...

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

If you knew people would pay extra for a bald dragon, could you pick which parents you should breed in order to get the highest number? The unit examines heredity and genetics through breeding dragons, mice, dogs, and tries to figure...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

It's alive! Young mad scientists create monsters as they explore the probabilities of genetic traits during a well-structured inquiry lesson. Pairs travel from station to station, rolling the dice and adding traits to their creations as...

We all drink milk as babies, so why can't we all drink it as adults? Examine the trend in lactase production on the world-wide scale as science scholars analyze and interpret data. Groups create pie charts from the data, place them on a...

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...

Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could...

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...

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...

Easy-to-read notes about Mendel's Laws of Heredity make up this collection of slides. In bullet-point style, viewers are exposed to Mendel's pea plant experimentation and the rules he developed that govern genetics. There are no graphics...

In a world of DNA testing popularity, understanding how to solve basic genetic problems allows scholars to better understand and interpret test results. They work through many different types of genetic problems using statistics, Punnett...

Two fish appear different, but how do scientists determine their genotypes? Scholars practice performing test crosses to determine the genotypes of fish given their phenotypes. They answer in-depth comprehension questions and complete...

Students explore the concepts of phenotypes and genotypes.  In this genetics activity students work together to pick a superhero and determine the traits of the offspring. 

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

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...

Practice calculating genetic probability, listing gametes, and identifying genotypes. The worksheet combines short answer questions with practice problems to solve. It would make a revealing review assignment or even a practical pop quiz...

For 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...

Investigate the Hardy-Weinberg Principle to explain genetic equilibrium. The 10th lesson plan of a series of 12 is a laboratory exploration of genetic equilibrium. Your classes use a mixture of beans to model allele and genotype...
