Question

ructions for Meiosis sketching 1. FOLLOW INSTRUCTIONS wnload and print the Melosis sketching sheets from Canvas, Modules, Corona (or make your own but please be NEAT and make them exactly as I have them). 3. Start with a cell from a sexually reproducing organism that has three homologous pairs. I have drawn that cell. It has each homologous pair represented as a unique size and shape and each pair has one labeled with an asterisk (originating from the mother's DNA) and one unlabeled (originating from the father's DNA). DNA replication has not occurred yet in the cell I have drawn. You can tell because there are no sister chromatids!!!!!!!!!!!!!!!!!!! 4. You need to draw the cell as it would appear if DNA replication occurred. One homologous pair would look like this: DNA replication hybrid 5. Perform one crossing over on one of the homologous pairs. So it should look something like this: Include your hybrid sister chromatids in all of the subsequent drawings not 19 not a hybrid Cross- sister over chromatids hybrids ** 6. Then draw the four possible metaphase alignments. The next page of this doc shows them AND you should notice at the bottom that flipping the cell upside down is still the same alignment. 7. Now take each metaphase alignment and proceed through the rest of Meiosis I. From Metaphase alignments.you will end up with 2 cells in Telophase: (on page 1); From Metaphase alignments.you will end up with 2 cells in Telophase 2 (on page 2) etc. 8. On page 5 you will begin to move through meiosis Il. On page 5, use the two cells from telophase and proceed through Melosis ill. You'll end up with four cells. Then use the two cells from telophase and proceed through Melosis il. You'll end up with four cells. 9. On page 6, use the two cells from telophases and proceed through Melosis il. You'll end up with four cells. Then use the two cells from telophase, and proceed through Meiosis II. You'll end up with four cells. 10. Now count the number of different possible cells produced from meiosis of a parent cell with 3 homologous pairs assuming only one crossover. Report that number as MY ANSWER - Jon page 6. 11. Scan, take a pic or otherwise upload pages 5 and 6 with your answer. 12. Take the meiosis quiz.

Hence, MY ANSWER =32.

Therefore, 32 different cells are produced from meiosis of a parent cell with 3 homologous pairs of chromosomes, assuming only one crossover.
