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

Using the Internet to Do Punnett Squares
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...

Incomplete Dominant and Codominant Traits Worksheet
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,...

"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...

Mendelian Genetics
How did Mendel know which pea plants would demonstrate certain characteristics? Pupils explore the answer this question, among others, as they complete Punnet squares, research dominant and recessive traits, and explore hereditary...

Roll of the Genes
Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...
Curated OER
The Blue Genes Challenge
Learners practice completing and analyzing Punnett squares. They create Punnet squares in response to a provided scenario from the company Blue Genes Incorporated. In addition, they complete an activity to determine the phenotype of...

Lesson 8: Genetics Problems
Students predict the characteristics of future offspring using punnet squares. In this genetics lesson plan, students explore monohybrid crosses using an interactive website. They research about causes of blueness in people.

It's All in the Genes
Twelfth graders investigate the inheritance of traits through several hands-on activities that illustrate the transmission of genetic characteristics. Students study advanced topics including multiple alleles, polygenic traits,...
