Oh for goodness sake! Just encourage your children in their chosen path. They will have inherited genes from each parent, but there are a multitude of other factors which will determine who they are! I'm sure many of us with more than one child will have realised that actually, despite the same gene pool and upbringing, they have different personalities, different strengths, different interests. Thank god - I would hate to have a family where all my kids were clones!
FWIW, DH and I both have similar strengths and educational backgrounds - I did English Lit at Bristol, he did Eng Lit at London, we both did postgrad studies, I worked in law, both now work in an educational sphere... but this doesn't mean to say our children are going to follow in our footsteps, in fact one of them is clearly moving in a Science/Maths direction.
If you have particular ambitions for your child to go to a particular type of University/do a particular degree/have a particular career, I suggest you go and do it youself, rather than living your life second hand through them!
I loved University, but as I said in a previous post, it's not the same as it was these days - no more grants as I had, it means racking up masses of debt. Also when I went, it was a way of moving away from home, having those life experiences that you didn't get living under your parents' roof, becoming independent. Not like that now - life has changed, young people don't need to move 100 miles away to have the freedom that we did. They also often can't afford to move away anyway. University has become a different beast. Fine if it suits you, but not the passport to what it used to be.
