Can a cognitive pattern be related? Absolutely, I'm sure in some circumstances. But not in all circumstances. In the jobs you mentioned I already see a lot falling into the 'savor/hero' complex of wanting to save everyone.
Some daughters follow the family footsteps into military, firefighters, police, even construction. I think those jobs are more women-heavy now because of equality. Why was it more commonplace to previous and current Communist countries? Perhaps those countries actually had more equality in jobs out of some sort of necessity or it began after a war, as you mentioned WW2 which had that same effect in Western countries too.
I think parental relationships have a huge impact. Early life trauma. Creative interests in pursuing something considered inappropriate for a girl. (I wanted to take drafting and pursue architecture. My mother forced me to take typing so I would "always have a job because architecture is a man's job.) Our family has a huge influence on who we are. This is not something that can be assumed because each soul's journey has been unique. The reasons for their behavior are just as unique, as no two people have the exact same experience.
