Genes, Environment, and Your Traits

Your DNA is actually not the only thing deciding your future. Most of your traits, like how tall you

are or how smart you get, are what scientists call multifactorial. It means there isn't

just one gene running the show, but hundreds of them mixing with your environment.

This is why super tall parents can have average-height kids, a concept called

regression to the mean. Even identical twins don't have the same fingerprints because

the patterns depend on how they touched the womb wall before birth. You are basically

a remix of your ancestors and your lifestyle.
