GENETICS - BIOL 97    Homework due 8/30/07

Part I.  Find and define vocabulary in Chapter 1 of the textbook.  These are typically the terms in headings and/or emboldened.  As you peruse the chapter, pick out any terms with which you are not familiar and look them up as well.  

Recognize the names of the organisms mentioned in Chapter 1, and their classification, e.g. prokaryote or eukaryote; plant, animal, fungi, or protist; among plants: angiosperm or not; among animals, phylum; and among vertebrates, class.

Be prepared for a quiz on this vocabulary, cell structure, the main distinctions between prokaryotes and eukaryotes,  and these organism classifications.

Part II.  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.
