GENETICS - BIOL 97    Homework 3:  due 9/1/09

Using the text and any other sources you choose, sketch the phases of

1.    mitosis

2.    meiosis

3.    meiosis with one single cross-over event

in a “typical” 2N animal cell.  Be sure to indicate (in the sketch) how any and all cellular components are changing during these phases.   [So you will have three series.]

**    The cell has 1N = 2
**    with one smaller acrocentric chromosome and one larger metacentric chromosome
**    Use color to distinguish the maternal and paternal chromosomes.

**    include all subphases (specifically in prophase I)
**    label each drawing
    **    each drawing has a title (phase or subphase)
    **    label each structure in every sketch, or at least every time it changes appearance
**    If you choose, you may magnify a component or structure to show important features, rather than magnify the entire sketch.  Be sure your labels are clear.
