Do you think your parents' types molded you?

I truly believe that my parents and big brother's types molded me.
Dad: INTJ
Mom: ESFJ
Bro: INTP

If my dad had been an F, my brother would've been an F and I would've been an F.
Not sure about the rest...

Mon: ISTJ
Dad: Passed before I knew about types, defiantly an F tho
Twin Brother: ENFP

Aren't our types mostly determined by genetics and womb conditions?

Via twin studies we now assume that nature(genetics) plays a larger part in determining personality then nurture(how we are raised). Additionally the amount of testosterone that that we are exposed to in the womb seems our "masculine" and "feminine" traits, with more testosterone leading to stronger masculine traits. So my theory is that more testosterone leads to stronger T function and maybe other differences. So once you are born you have a template of a personality and then nurture takes over to determine how well you will fill that personality out.

Many people claim that we can not change our types, I don't know if this is true but it does seem to support my theory.

Non-genetic relation to my parents, but I feel environmental factors contributed to my development and enneagram type as well...
Mother: ESFJ The Caregiver
Father: ISTJ The Duty-fulfiller
Me: ENTJ
Sister: IXFX (also non-genetic)

Interesting! I was thinking about that too but you laid it out nicely! Physiologically, the high testosterone exposure in the womb is also manifested in my physical traits. Plus, I tend to "talk less," "observe more," and "do more," which I find are masculine attributes. These are consistent with your personality formation theory.
