organism's genetic makeup; "blueprint" ; hybrid inheritance of hereditary traits and environmental factors
organism's observable physical characteristics; also chemistry and "wiring" of brain
deoxyribonucleic acid; a molecule that stores biological information of the genetic code
segment of a chromosome that encodes the directions for the inherited physical and mental characteristics of an organism; functional units of a chromosome; specify the operation of a single protein; 30,000 in total human body
tightly coiled threadlike structure along which genes are organized; consist primarily of DNA; 23 pairs in every nucleus in the body

named for X and Y shapes; carry genes encoding for male or female phenotype; one X from mother and X or Y from father
nature vs. nurture
heredity and env. always work together to influence behavior and mental processes; even identical twins have differences in appearances and personalities
extra chromosome 21; impaired physical development and mental retardation
choosing your children's genes
Human Genome Project; genetic manipulation in people; cure physical and mental disorders, but could also be used to select sex of a child, and maybe one day select specific genes for a child
