Review of Class: Nov. 28

In class today we took notes and learned about meiosis cell division. All of the notes from class are up on moodle. To briefly summarize, meiosis is the division of haploid cells. Haploid cells are the cells that contain half of the original amount of chromosomes, which is 23 chromosomes in humans. Another important fact about meiosis is that it only happens in reproductive cells, which are the sperm and egg cells. The video below sums up the process of meiosis:

I hope this video helped your understanding of meiosis. If not, then here are some links of more detailed videos of the stages of meiosis and sexual reproduction:

• Mitosis, Meiosis, and Sexual Reproduction: http://www.khanacademy.org/video/mitosis--meiosis-and-sexual-reproduction?playlist=Biology
• Phases of Meiosis: http://www.khanacademy.org/video/phases-of-meiosis?playlist=Biology
• Difference between mitosis and meiosis: http://www.youtube.com/watch?v=Ba9LXKH2ztU&feature=results_main&playnext=1&list=PLC7DDC2846B1BF913

Hopefully these three links will help you understand meiosis even better. Personally, I recommend the first two videos because, they were very helpful in my understanding of meiosis, and also the various definitions like zygote and homologous.
