A diploid organism has chromosomes. Use colours or symbols to show which chromosomes are which throughout each stage. Draw and label the chromosomes, sister chromatids, centromeres, spindle fibres, tetrad, crossing over and nucleus where appropriate.

For an organism with 3 pairs of chromosomes (6 total chromosomes, 2n = 6), draw chromosome diagrams for the following phases of the mitotic cell cycle: G1 of interphase, prophase, metaphase, anaphase & telophase. Be sure to draw the correct number of chromosomes and the correct number of chromatids per chromosome. Use a different color to represent each chromosome type (for example, use blue to indicate all copies of chromosome 1, red for all copies of chromosome 2, & green for all copies of chromosome 3).
