Meiosis- Sam Studer

Key Things:
• 4 daughter cells
• Daughter cells are genetically different
• Daughter cells are haploid (23 chromosomes)
• Sexual aka gametes

Stages of Meiosis:

Meiosis 1:

1) Prophase I- Chromosomes become visible; crossing over occurs
2) Metaphase I- Pairs of homologous chromosomes move to equator of the cell
3) Anaphase I- Homologous chromosomes move to opposite poles of the cell
4) Telophase I- Homologous arrive at opposite poles and cytokinesis 1 occurs

Meiosis 2:

1) Prophase II- Chromosomes in both new cells prepare to move to the equator of cell
2) Metaphase II- Sister chromatid line up at equator
3) Anaphase II- Chromatid move to poles of cell
4) Telophase II- Nucleus divides (cytokinesis 2: cytoplasm divides)

Simple Version of Meiosis:
Interphase, Prophase, Metaphase, Anaphase, Telophase, Prophase II, Metaphase II, Anaphase II, Telophase II

Reflection:

While looking at meiosis I found out that there is a lot to be said about meiosis but really there is only a few things that you should know every time meiosis comes up. Some of the things that you need to know is are: it's sexual, 4 daughter cells, 23 chromosomes, haploid, sperm & egg, and genetic variation. If you remember these things for meiosis, you will 90% of the time get all the answers right on this topic. Also, you will need to know the definition. The definition of meiosis is the process in which gametes (sperm & egg) are formed through sexual reproduction. While looking at things on this topic I didn't really find anything on this topic surprising. I believe I know this topic very well and think that I can answer most to all questions asked about this topic. To me, this topic is interesting for me and I like it because I think that the ways that a cell divides to make more cells is fascinating and I will being to know how a cell divides in my career that I want to pursuit in. In the career that I want to pursuit in requires me to monitor different things in the body like heart beat, blood flow, etc. With monitoring these things I need to know if something isn't right and how I could fix it. With that, there could be something happening to there cells dividing and I would need to fix it right there.
