I understand that both environmental and genetic factors affect a person's height. There is a belief among most people I've talked with that given that groups of ethnic peoples eat the same diet, that the different ethnic groups will have varying and predictable heights, based on their race.
For example, my friends believe people of African descent will be tall as will Scandinavian descendants. However, they believe people of Asian descent will be shorter. I wonder if there is a section of DNA discovered that determines a person's height and if indeed a person's race is a good indicator of their height?

I have red hair and when got my wisdom teeth removed, my father told me that they had to use more than the regular amount of anesthetics usually needed. At first, I thought nothing of it. Then, when I later started a research paper on red hair, I found out that people with red hair generally need around 20% more anesthetics than people with other hair colors. Why is that? Is it because my MC1R gene is mutated, or is it something else completely.

March 21, 2012: I am wondering about intelligence and genetics. More specifically, the relationship between parent's intelligence and their offspring. If a really smart person and a not-so-smart person have a child, what is likely to happen genetically? Also, is intelligence more of a genetic or environmental trait?
