Science what i learned about heredity and traits.

From the reading I learned that our DNA is 99.9% similar. I found it astounding that through all the differences of height, skin color, eye color, and hair color that our DNA could be that similar. Also i learned that each parents sex cell has 23 chromosomes that they will pass on to you. Adding those together makes a total of 46 chromosomes. What I didn't know though was that with each set you HAVE to get one of those from each of your parents, you get only get both parts of the set from one parent. In conclusion I think was a very interesting and educational website and will help in future understanding of this topic, should I need it.
