Genetics

(Science: study) The study of the patterns of inheritance of specific traits. Relating to genes and genetic information. Also known as heredity. Modern theories explain how traits are passed down from parent to offspring. The first to test this theory was gregor mendel, a monk from Austria who tried to explain why some pea plants were short and some were tall, but none were in between. He placed nets over the plants so no bees or flies could pollinate the plants. Pea plants are one of the few plants capable of self pollination, so Mendel tried this with short plants and all were short, so he expected that the same thing would happen with the tall plants. But when he tried it, 75% were tall and 25% were short. This was when he used a punnett Square. A punnett Square is a model used to predict the possible outcomes of offspring.

Re: Re:

Unless you're suggesting that some "races" have better genetics than others. Allele frequencies vary between poopulations. The question is not whether there's a difference (in genetic IQ predisposition), but how large that difference is. I think ...

Brain size=IQ level theory (Blacks vs Whites & Asians)

No one doubts that genetics play a vital role in intelligence. But we're all creatures of genetics, aren't we. Unless you're suggesting that some "races" have better genetics than others. If that is indeed the case then the ...
