Meiosis Revisited

9/11/2018

0 Comments

 
In class today we finished our "Genes in my Body" Diagram and continued our exploration of genetics.
Also, if you didn't do as well on the back page (meiosis section) of the quiz. An alternate assignment is at the bottom of this post for you try try again. 
Picture
Meiosis Alternate Assignment: Watch the video below and answer the following questions. You can turn them in to Mr.Powell in class or email them to [email protected]
​1: What kind of cells are made during meiosis?
2: How many chromosomes are in most human cells?
3: Why are there only 23 chromosomes in sperm and egg cells?
4: Why do we call meiosis a "reduction division?"
5: Why can siblings with the same parents look so different from each other?

Today we tried our hand at breeding drakes and also got our first glimpses of a process called MEIOSIS. Meiosis is the process by which parents produce GAMETES that will fuse to become a ZYGOTE, the first complete cell of a new organism. You can learn more about meiosis in the video to the right.
