Purpose
Now that you've learned about mitotic and meiotic cell division, you understand that the process of mitosis results in cells that are identical to the parent cell whereas in meiosis, the daughter cells that are produced are genetically different from the parent cell. Meiosis introduces variation into populations of sexually reproducing organisms while mitosis produces cells for growth and cell specialization. In this post you will demonstrate understanding of how meiosis contributes to genetic variability and why this variability is important.
TaskThis week’s discussion involves 2 parts. Be sure to respond completely to the prompt in your post.
- Part 1: Compare and contrast the differences in mitosis and meiosis.
- Part 2: There can be mistakes or errors occurring during the process of meiosis. When this happens, what is the result? Provide a specific example/condition and explain. Be sure to cite your sources accordingly.
NOTE: In order to create discussion "threads" or a continual discussion among groups of students, be sure to add a question at the end of each post. Please remember to reply to at least 2 peers.
Grading Criteria
- Your understanding of the role of meiosis in creating genetic variation during sexual reproduction.
- Your peer responses are substantive and thoughtful and advance the discussion by introducing new insights or perspectives, and/or significantly deepening or broadening the conversation with questions.
- Your use of language: your writing should be clear, well-organized, and free from spelling and grammar errors. Citations should be used when necessary.
