MEIOSIS
FUNCTION: process of turning ONE cell into FOUR individual cells
- sexual reproduction
- process in which gametes (sperm and egg) are formed
- cells are NOT identical which gives genetic variation
- haploid - half the chromosome number
- goes through two cycles
MEIOSIS 1
prophase: nucleus starts to disappear
metaphase: the chromosomes line up in the middle of the cell
anaphase: chromosomes begin to split apart
telophase: chromosomes move to opposite ends of the cell and two nuclei are formed
cytokinesis: where the cytoplasm divides creating two cells
END RESULT: two daughter cells are formed
MEIOSIS 2
prophase 2: nucleus starts to disappear in two new daughter cells
metaphase 2: the chromosomes line up in the middle of the cell in the two new daughter cells
anaphase 2: chromosomes begin to split apart in the two new daughter cells
telophase 2: chromosomes move to opposite ends of the cell and two nuclei are formed between the two daughter cells
cytokinesis 2: cytoplasm divides in the two cells creating four cells
END RESULT: four genetically variated daughter cells are formed

What I Learned
I learned that meiosis is a form of sexual reproduction which causes genetic variation. Meiosis goes through 2 cell cycles which allow for more genetic variation and 4 new daughter cells. The only way for meiosis to occur is if two gametes form together (fertilization). Meiosis forms sex cells. These sex cells are genetically variated because of mutations, crossing over and nondisjunction.

Your blog post is very well thought out. I love how much information you included. Your reflection helped me a lot. It completely summed up the idea of Meiosis which I seem to struggle with. The only thing you could of added is an interactive, video, or quizlet.
ReplyDeleteThe layout of your page and your visual made this topic very easy to understand. I like how you explained what meiosis is in your reflection, it was simple and to the point. I would add what the mutations, crossing over, and nondisjunction actually are so you would know what they are when you come across them.
ReplyDeleteI really like the cell picture that moves and shows each stage. Did you like doing this subject or was this just easy for you to do? You should add explanations for mutations, crossing over and nondisjunction.
ReplyDeleteI love the pictures and the gifs you used because I'm a visual learner, and this topic was hard for me when reading the explanations so seeing it was better. I wish I had seen your reflection when first doing this topic so that I could know what meiosis was because it basically sums it all up. I would say add a video or game a reader could go through to break down the process themselves.

I love the animated pictures it really helps me to get a better understanding of the process and what is going on! Your reflection helped me get a better understanding of the process and what is going on during Meiosis. Maybe you could have added in the differences between Mitosis and Meiosis some!
ReplyDeleteThe way this blog is organized is very neat and not cluttered. The information is straight to the point and gives the reader all they need to know. Overall, you did a wonderful job. Also the GIF's were a very nice touch.
