Meiosis vs. Mitosis

For cells, there are two different ways of duplicating. First, there is mitosis in which cells duplicate their DNA and then split into two identical cells. This requires only one cell. The other way of cellular reproduction is called Meiosis. In Meiosis the DNA duplicates and then splits into two cells. Those two cells then split once again (without duplicating DNA) leaving you with four different cells with only 1/2 the proper amount of DNA in them. This involves two different organisms. They only have half the DNA because when they combine with the other haploid (1/2 DNA) cell it will have the correct amount of DNA. In conclusion, there are two different ways of cellular reproduction: Mitosis and Meiosis.















 
 I found this video especially helpful in  explaining the process of Meiosis and explaingin all of the vocabulary concerning the cell division. It shows how they trade genes and divide. 
This is another video I found. Its a fun way to remember Meisosis and has good visual representations.



This is another video I found. Its a fun way to remember Meisosis and has good visual representations.It clearly demonstrates the process of the cell division and uses Vocabulary.
