Can someone give me an explanation of meiosis?

Hi there!

Meiosis is a type of reproduction where two divisions occur. It is when gametes, sex cells, divide. In prophase of meiosis, it is similar to that of mitosis, as in the spindle fibers develop as well as centrioles. First, homologous (pairs) of chromosomes line up in the center of the cell. Next, spindle fibers pull the pairs apart, leaving one chromosome of each pair on each side. Then, the nuclear material divides as the spindle fibers and centrioles go away. Lastly, the cytoplasm divides, leaving two cells. Meiosis two starts out with prophase again. In prophase, the DNA condenses and forms short chromosomes as well as spindle fibers and centrioles developing. Next, the chromosomes (there is only one chromosome, made up of two sister chromatids) line up in the center of the cell. Next, the spindle fibers pull the chromosomes apart, pulling one chromatid to each side of the cell. Then, the nuclear material divides and the spindle fibers and centrioles disappear. Lastly, the cytoplasm divides, leaving four cell in total.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
