I'm pretty sure that males have masculine forms, and women have feminine forms. How they behave might be a different matter, tho.
@sim
More than anything biology probably determines who one decides to imitate.
@sim
A young boy would probably be more predisposed to to imitate his father than his mother would be my guess. We do know that people tend to make friends with or at least hang out with people who look similar to them later in life, so I would also assume they would then dress like them, talk like them, and imitate certain mannerisms and behaviors in order to fit in.
@sim This is indeed a wonderful question. I think it depends whether or not that person has much contact with other boys or men outside of the home.
