Curated OER
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,...

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...
Curated OER
"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...

Oompah Loompa Genetics
In this genetics worksheet, students use descriptive information about the different types of Oompa Loompas to show genotype and phenotype plus dominant and recessive traits. This worksheet has 12 problems to solve.
