Document Summary

Our physical development is in large part directed by an elaborate genetic blueprint passed on to us by our parents. Our genetic endowment combines with environmental forces to determine our behavior: nature or nurture is not an appropriate dichotomy; it should be nature and nurture. Gregor mendel"s research marked the beginning of modern genetic theory: genotype: the specific genetic makeup of the individual. Never change: phenotype: the observable characteristics produced by that genetic endowment. Influence the development, structure, and function of our body, including our brain, by controlling the production of proteins. Heredity encoded in combinations of bases adenine, thymine, guanine, and cytosine. Genes contain bases, carry codes for protein manufacture. Every cell has 46 chromosomes (23 pairs: egg and sperm only contain 23 chromosomes, they combine to form a new cell (gamete) with 46 chromosomes. Human genome project was initiated in 1990. The mapping of the human genetic code was done by the international human genome.
