Curated OER
Inheritance in Maize
Students use mutant corn ears to investigate inheritance patterns. In this inheritance lesson plan, students count the number of corn kernels of each phenotype in mutant and wild type ears of corn. Students calculate the ratio of...
Curated OER
More Zork Genetics
In this genetics worksheet, learners complete 3 dihybrid crosses of traits to determine the probability of the genotypes and phenotypes of the offspring of the imaginary species, the Zork.
Curated OER
Genetics Worksheet
In this genetics worksheet, students answer a variety of questions about genotypes, phenotypes, genetic inheritance, and traits. They solve for the probability of genotypes and phenotypes of offspring by completing monohybrid and...
Curated OER
Pea Plants Dihybrid Cross
In this dihybrid cross learning exercise, students are given four crosses to complete using punnett squares. They determine the genotypic and phenotypic ratios of the offspring.

Khan Academy: The Law of Independent Assortment
Article defines Mendel's law of independent assortment, provides examples, and takes a look at how it is used to make predictions. Also, discusses dihybrid crosses and 4 x 4 Punnett squares.

Khan Academy: Probabilities in Genetics
Article reviews some probability basics then investigates how these calculations can be applied to genetics problems involving relatively large numbers of genes. Explores how the sum rule and the product rule can be used to solve these...
