Discussion Overview

The discussion focuses on comparing images of metaphase in meiosis and mitosis, specifically examining differences beyond the presence of crossover regions in chromosomes. Participants explore the implications of chromosome numbers and structural characteristics during these phases.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions the differences between Meiosis Metaphase II and Mitosis Metaphase, seeking clarification beyond crossover regions.
  • Another participant provides a description of the chromosome numbers in mitosis and meiosis, noting that meiosis results in half the number of chromosomes compared to mitosis.
  • A later reply corrects the previous claim by stating that in Meiosis II, the gamete is undergoing a process similar to mitosis, with only half of the chromosomes present at the metaphase plate.
  • One participant challenges the clarity of the original question, suggesting that important terms like "chromatid" were not included in the initial post.

Areas of Agreement / Disagreement

Participants express differing views on the specifics of chromosome behavior in meiosis versus mitosis, and there is no consensus on the clarity of the original question or the implications of the differences in metaphase images.

Contextual Notes

Some assumptions about the number of chromosomes and the terminology used in the discussion remain unresolved, which may affect the understanding of the comparisons being made.

What is the difference between the images of Meiosis Metaphase 2 and Mitosis Metaphase other than the fact that the chromosomes have crossed over regions.

Bad answer:
In meiosis you have one half of the number of chromosomes, all of the chromosome pairs moved apart from one another. In mitosis each chromosome duplicated itself, so you have the same number of chromosomes you started with. Meiosis you end up with one half of the number of chromosomes

Example humans:
start: one cell 46 chromosomes -> 2 cells with 46 chromosomes each This is mitosis.
start: one cell 46 chromosomes -> 2 cells with 23 chromosomes each This is meiosis.

oops I get what you are asking. In Meiosis II you have a gamete undergoing mitosis, so one half of the chromosomes are there at the metaphase plate.
 
No but you are not given the number of chromosomes. You are just told that the height of the sister chromatids is different
 
Please. Do us all a favor: paste the entire question so we all can see it. I do not see the word chromatid in your first post for example.
