In my religion there is no such thing as Santa. I don't believe in Santa. The reason why is he has to deliver presents to millions of kids and has to go to 91 million houses in 31 hours. He has to spend  1/1000th second per house. He has to go down the chimney, put the present down, and eat the cookies and the milk. He also has to go 625 miles per hour which would be like if an asteroid came down. 

DNA replicates and gets a copy from the original DNA. From the new copy it gets another copy, but gets different DNA than the parents. But the child will be looking like either look like the mom or the dad. Also they will be able to have stuff that the mom can't do, or the dad can't do. You will be able to have stuff either the mom or the dad can do.

There is a lot of base pairs that make up how you look and and what you can do. Like say if both of your parents can roll their tongue and then later on your are going to be able to roll your tongue. What we get from our parents are called genes. The four main things are Thymine, Adenine, Guanine, and Cytosine. The picture is a double helix at the bottom of this blog.They all pair up thymine with adenine and Guanine with cytosine. It is not that complicated.
