Um I think the other answer is right too but I also know this is part of it, genetic show our physical traits (how we look) the environment affects how we act and can often change our physical traits. Examples: I’d you are in an environment were you get a lot of sun you will be more tan. If you are in an environment where you would be active our being active is influenced on you then you would be more agile or fit. Etc. hope this helped
