What transmits from generation to generation

What I have observed is that,
There are 2 factors that determine a person’s actions:

# The situations/circumstance/surroundings/cultural-setups/environments (their adaption, fitting-in strategies, accommodation to all of that etc.)
# Their own interests/desires (which they pursue)

Generally, in the transmission from say parents to children (in the flow of genetic lineage),
Only the real essential desire of the parent is transferred to the child.
And whatever the parent did as adaptation, accommodation, and adjustment based on family/cultural/socio-political pressures of those times, does not pass over to the children.
This is because the children were brought up at a different world-time/age, with different family/socio-cultural/political/situational variables.
The world itself is at a different generation when the children are born,
And therefore the children adapt to those conditions,
And only the essential desires of the lineage continue through them.

For instance,
Say a father worked loyally in a single company all his life as a duty,
While the son decides to not work at all, and only work on his private passions.
On the surface, this looks like the father and son are entirely different.
But a more in-depth examination might reveal,
The father never had any real heart vested in the company affairs.
He may have done all of it from familial/moral/socio-cultural pressures,
While his real heart desire was in his personal interests.
So it is only the real heart desire that passes on to the son.
This can be taken much deeper than this,
But even now, with only this much penetration into the matter,
The son’s decisions do not look so outlandish in the light of this understanding, right?

Another instance would be,
If the mother dutifully married, had children, spent her whole life mixed up with them etc.,
Her daughter might take up a completely different meaning in life and become ultra career focused.
Again, on the surface, both look completely different.
But on deeper examination,
Maybe the mother, as an adaptation to her circumstances, went along with that wave,
But her real desire was to fuse her identity into something larger.
Her situation might have been such that the role of caretaker was what allowed her this larger experience and expansion.
So the daughter in alternate times, may seek to fulfill this same desire by absorbing herself into the corporate world and its goals (career).
It is the same desire expressing itself in 2 different situations and times.
This is actually still just slightly under the surface, but even this level of understanding reveals the continuity and similarity of desires passing through.
