We don’t get to choose our family, and by that I am referring to a little bit more than just a bratty little brother.
Genes are what make you who you are. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. There is nothing you can do about your genes, so before you start getting upset at your mom and dad, just remember that they were stuck with theirs too.
If a person is tall or short, wide or skinny, blue eyes or brown, it is genetics that determine these factors. And just like you have blue eyes like your mother does, so might you also suffer from their predisposition to suffer from acne. If you have a family history of moderate-to-severe acne, you have the greatest risk of developing it yourself, especially during your teenage years.
