In this meiosis activity, high schoolers read about the phases of meiosis I and meiosis II and simulate the chromosomes and chromatids in each phase. Students draw the changes in each phase and produce 4 cells with half the DNA in the end.

Learners examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess...
