Smart Boys

George and I talked about this some last night.

Nature vs Nurture… I tend to think of both as bottlenecks for human development. The debate about which does more to me makes as much sense as debating which is better for a web application: Apache or MySQL? Both are involved and affect the end results. The debate should be about how to leverage the synergy of both, but that is another blog post.

We humans have 46 chromosomes. 23 from each parent which come in pairs. Males have an XY pair. Females have an XX pair. Brain Rules was the first I’ve read that ~1500 brain-related genes are on the X and ~100 on the Y (and losing ~5 every million years). So the X chromosome is quite important for determining brain development.

For boys, the one X they have comes from the mother. Girls inherit an X chromosome from both her mother or father. To set up the strong potential of great genes for boys, look to women who are really intelligent. That tells you there is a 50% shot for the boy to get a good X. If both of the woman’s parents are intellectuals, even better.

Be smart about it though… Don’t make an IQ score for the parents part of a prenuptual agreement.

My mother has occasionally said things I enjoy remind her of her father. That’s a biased sample.
