Meiosis Lab: Building Baby Reebops
Students review the following vocabulary: Independent assortment, multiple alleles, and polygenic traits. They review their vocabulary by the "quiz, quiz trade" routine. Students work in groups. They are given one set of gene cards...

It's All in the Genes
Twelfth graders investigate the inheritance of traits through several hands-on activities that illustrate the transmission of genetic characteristics. Students study advanced topics including multiple alleles, polygenic traits,...
Curated OER
Patterns of Heredity
Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

Human Heredity II
Using deductive skills and reasoning based on the data provided about a family's blood genotype, blood phenotype, chromosomes, and genetic conditions, 9th graders answer the questions below. The conditions discussed are Down Syndrome and...
