Tendencies don't have to be heritable to be inborn. Nor do they have to be expressed to be heritable.

- cj 17y agoHow can something be inborn without being heritable? (Unless something is considered inborn if it is taught extremely early in life...)
- pg 17y agoIf it happens as the fetus develops. DNA doesn't specify the exact composition of a human down to the molecule.
- sjf 17y agoIf a trait is determined by a mutation it is inborn but not inherited. This is one possible explanation, but I am not a biologist, and I am not sure when the op intended.
- lkozma 17y agoOr if a trait is a composite effect of 'sub-traits' from both parents. It is inherited in its parts, but neither parents have the whole trait. What I mean: your dad has A, your mom has B, and AB leads to the successful trait.
- apu 17y agoWhy do different kids of the same parents have different personalities? Presumably they're "wired" that way from birth, yet it's not necessarily inherited directly from one parent. Genetics probably plays some role (as it does in almost anything), but it doesn't have to be the sole determining factor.
- cj 17y agoDifferent kids of the same parents have different genetics. When people have kids that aren't twins, each kid has a uniquely different combinations of genes, which could result in differing personalities as a result of inheriting a different combination of genes from the same two parents. Of course, people's personalities are influenced by their home life, their experience at schools, and their experience growing up with siblings (which is different amongst kids of the same parents) among a huge range of other variables. I suppose the making of an entrepreneur is similar.
- bokonist 17y agoPerhaps a better word would have been "intrinsic". A trait can be a result of compounding, non-shared environment. For instance, at any early age you might have recieved a reward for taking a risk. Perhaps that led you to take more risks, and achieve more rewards. Then you join a social group in which you develop a niche as being the guy who always takes crazy risks. As a result of this, by age 20 being a risk taker is built into your personality.
- cj 17y agoI agree with this type of interpretation, although I would struggle to call it inborn or even intrinsic. I still see this as a type of learning, albeit from an extremely early age.
