Product Details

Teach meiosis terminology using this simple hands-on simulation kit. Students string alleles (pony beads) onto chromosomes (chenille wires) and mark the beads to create a unique gene sequence. Then, students crossover sections of the chromosome and complete the phases of meiosis. The student handout includes detailed information about meiosis with simple step-by-step instructions to facilitate true understanding of this complex biological process.Completely reusable kit with enough materials for 30 students working in pairs.
