For up to 32 students working in groups of 4. This is a complete genetics lab for advanced high school classes or introductory college-level classes. It covers the basics of mendellian genetics, including segregation and independent assortment of alleles, dominance, genotype and phenotype, expected ratios, monohybrid and dihybrid crosses, and chi-square.

Students first study 2 monohybrid crosses in corn, and use Punnett squares to diagram the crosses and make predictions about the F₂ resulting from each cross. They score phenotypes, compare their data to expected results, and draw conclusions.

Building on their results, students are then asked to consider a cross that combines the 2 sets of alleles involved in the monohybrid crosses (i.e., a dihybrid cross). Students again construct a Punnett square to predict the F₂ and collect data to test their predictions and draw conclusions.
