Genetics and the Work of Mendel
Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...

Science Lesson for Grade 12
Twelfth graders perform dihybrid crosses and calculate phenotype and genotype ratios. In this series of science lessons, 12th graders explain the process of anodizing aluminum. They research on the benefits and harm caused by resonance...

Solving Crosses
Genetics hopefuls solve Punnett Squares for monohybrid and dihybrid crosses. An example of each is provided to teach the process. Other heredity patterns are mentioned and genetic disorders are listed in the second half of the...

Dihybrid Punnett Squares
Students construct Punnett squares to illustrate specific genotypic and phenotypic genetic outcomes.
Students calculate the probability of achieving specific genotypic and phenotypic genetic oucomes, using dihybrid Punnett squares.

Yeast - A Dihybrid Cross
Students make a yeast dihybrid cross and follow two forms of each of two traits: red growth versus cream color, and tryptophan-dependent versus tryptophan-independent.
