All preferences as multiple-allele, J vs. P with P being recessive, S vs. N with N being recessive, F vs. T with T recessive, E vs. I with I being recessive. Though, the only preference where I can see evidence of one being recessive is N. Also, maybe T vs. F is tied to gender.
Bull! I don't think there's a recessive vs dominance in any of the letter preferences... For sure I/E isn't dominant recessive. There's a heavy genetic component, but introversion is not recessive. It's more like a graded co-dominance. Kind of like height
All functions multiple allele, with expression of function being recessive.
What do you mean by expression of function being recessive? I'm confused...
Grandfather: ?STJ (died when I was 6, never really knew him, always seemed to be a ?STJ when my mom told about him)
Grandfather: E?Fp? (can't remeber, he died when I was 3 years old, but when my dad tells about him, he seems like a E?Fp to me)
Aunt 1: ESFP
Aunt 2: E??J? (she's hard to type)
I was sitting outside the classroom waiting to go in, and I saw an airplane hit the tower. The TV was obviously on. I used to fly myself and I said, "There's one terrible pilot."

There is evidence to suggest that higher levels of testosterone in the mother's womb will lead to development of a "male-brain". Even in a female.
These levels are predominantly genetically determined ( in the mother) although the effect is an environmental one ( but not strictly nurture).
I red this thoery once in an evolutionary psych book-that stress during moms pregnancy causes testosterone levels to decline, thus a boy babay could be a boy, but have a more girl-like brain, and the opposite could as well.
Also another cool Nature paper looking at Thinker-Feeler (they called it male-female) diffs in brain structure, by looking at a survey measure of empathy vs a survey measure of analytical IQ and coorelating with braoin structural diffs on ave in populations.
On one extreme was aspergers and austism, where increases in the white matter can be seen, and the other extreme was increased corpus collusum interconnectivity in femals (on average).
The paper was pretty interesting however I very likely muddled the description as I have forgotten most everything I ever knew...
points to a heck of a lot of nature but with epigenetic/biological inflnces playing a role as well,
I am fairly certain about all of these types.
I'm not sure how much of it is due to heredity.
I just know that when there's conflict, my twin sister is the first one to get overemotional..my mom and dad have a classic Guardian/Artisan relationship.
My mom wants to plan everything and is a neat freak while my dad prefers to wing it and is more disorganized. My mom disapproves of a lot more but my dad has more of a temper while my mom will disapprove in a calm and stern manner- so yea- don't get on either parent's bad side.. but if I want to do something fun, I'll ask my dad first.
This is kind of fun.
Let's see for other family members.
Maternal grandmother: ISFJ
Maternal grandfather (deceased): ISFP or ESFP (I lean towards ESFP- he seemed more ISFP but I realize due to his older age- he simply didn't feel like doing as much anymore and spent a lot of time by himself watching TV.)
I don't know anyone on my father's side too well.
I only met his brother and his family once. I'd say a family of somewhat snobbish Guardians.
His brother could be a Rational or Artisan- since he quit his high-paying job as a lawyer because he was just so much smarter than everyone else... but as an ENTP, I wouldn't quit a sweet job simply because I thought the people I worked with were 'beneath me'- that seems to be an irrational decision.. he now is in charge of a smaller firm (which is great) but the reasons he left show somewhat of an arrogant side..
Knowing my dad, who doesn't like or trust people who put on airs, I could see why they drifted apart..
The only person my dad was close to from his family was his dad who passed away three months before I was born. His mom passed away when he was a teenager. However, from what I heard about him and seeing him in home videos, my guess would be ENTP.
