Human Genetics - Mitosis and Meiosis
Using the text and any other sources you choose, sketch the phases and sub-phases of
3. meiosis with one single cross-over event
in a “typical” diploid 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 2 colors to distinguish the maternal and paternal chromosomes.
☞ If there are alternate outcomes (such as segregation in meiosis I) show both alternatives
★ include all subphases (specifically in prophase I)
▸ leptotene stage
▸ zygotene stage
▸ pachytene stage
▸ diplotene stage
★ 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.
