Curated OER
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...

Monohybrid Punnetr Squares
Students explore Punnett squares and illustrate specific genotypic and phenotypic genetic outcomes. After a class discussion, students predict the probability of a specific trait being passed on by using Punnett squares. They reveal the...

Principles of Heredity
Students model traits on genes using colored paper and tongue depressors to represent chromosomes. In this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits, recessive...

Complete Dominance Traits
In this instructional activity, 10th graders produces a different phenotype since the dominance is incomplete. Both parents have a spotted nose. After student have determined traits, they create drawings. Students chart thier respones...

Dna From the Beginning: Genetic Inheritance Follows Certain Rules
Find out what happened when Mendel crossed two hybrid pea plants. The animations do a good job explaining why these crosses produce a 3:1 ratio of traits.
