We know that female brains are different from male brains in their functionality, so perhaps there is some evidence that biology plus social forces such as parental pressure affects the path we take. No one will dispute that the sexual division of labour runs along fairly clear gender lines. Men are predominant in competitive, risk-taking jobs in finance or with machinery. Women who excel in maths, physics and engineering have reported a high degree of family freedom for the female child to choose and not be pressured to undertake a traditional female career. The right and left hemispheres of the brain are more integrated.
Males are object related, competitive, take more risks and have better spatial skills.
What is really amazing to discover is that regardless of your physical gender, you can have a female or a male brain. Recently a test was devised to identify what kind of brain you might have. It's called Dichotic Listening. You wear headphones and a series of syllables are fed through. Sometimes simultaneously, sometimes singularly.
