Students use physical models of chromosomes to explore the topics of meiosis and genetic variation. First, students use “paper chromosomes” to model the independent assortment and inheritance of fruit fly chromosomes.
Fruit flies are a good candidate for a modeling activity since they have only 8 chromosomes, compared to 46 chromosomes in humans. Analyzing the variation in the phenotypes of five virtual offspring flies provides a springboard for students to connect the events of meiosis with its purpose of creating haploid cells and with the genetic variation that results from sexual reproduction.
