What else did he do to look very different

Answer:
Explanation:
This is a great question! There are two main reasons you two do not look alike. The first is that the two of you didn't grow up the same way. And the second is that even though you have the same parents, you don't have the same genes.
Different Environment
The way you grew up is what geneticists call your environment. It includes where you grow up, what you eat, and what you do. It also includes what your mom did and ate while she was pregnant with you.
All of these things play a role in the way you look. People are different in part because no two people grow up in the same environment. Not even twins are together all the time!
One example of how your environment can affect the way you look is in your height. There are certain periods in your life when what you do plays a big part in your height. Two of these times are when you are first born and when you hit puberty.
If you do not eat well during these two times then you will be shorter. But if you eat well then you will be taller. Extreme examples of this include neglected kids and kids in war zones. They tend to be much shorter than average.
There are lots of other traits affected by the environment. Things like personality, weight, and intelligence just to name a few. While the environment is important, getting different gene versions from your parents is probably an even bigger reason for why you and your brother ended up so different.
Different Gene Versions
Your genes play a big role in making you who you are. The color of your hair, the color of your eyes, and the dimples on your cheeks are all controlled in part by your genes.
At first it might seem like kids from the same parents should look alike. After all, kids get their genes from the same parents.
But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different.
