A somatic cell from a diploid species with 2n=4 (4 chromosomes or two sets of homologous chromosomes) is undergoing mitosis. Draw the cell and chromosomes during G1, during G2, during metaphase, and the two cells that result from mitosis at the end. Label each stage in your drawing, and also label sister chromatids and homologous chromosomes as appropriate.
