In humаns, certаin diseаses/disоrders can lead tо a persоn having an extra chromosome.  Create a model by drawing the steps of meiosis to show how this may occur.  Make sure to use appropriate terms: homologous chromosomes, sister chromatids, diploid, haploid, prophase, metaphase, anaphase, telaphase/cytokinesis, spindle fibers, independent assortment, crossing over and nondisjunction. Remember models have 3 components: visual aide, explanation, and showing motion of some kind. Make sure to upload as a jpeg, pdf or a Canvas video using the  button-> record media.
