Gene: chemical unit of heredity acgtag; acctag 2 genes w/ c & g alleles 1 & 2. Phenotype: observable (physical) look of organism; may not reflect total genetic composition. Homozygous: 2 identical genes/alleles in corresponding locations on chromo"s. Heterozygous: diff genes/alleles in corresponding locations on chromo"s. Chromosomes: contain genes that transmit traits from gen to gen (w/i nucleus) Crossing-over: exchanges of sections of chromo"s from 1 chromo to another . Anthropology: humankind in all times & places. Uniformitarianism (geo): earth always shaped/reshaped by nature over vast time-periods. Genotype chromosome 2 chromatids genes alleles dna. How anthro studies humans = distinguishes it from alt disciplines that study humans; looks @ both current & distant-past humans. Bio-perspective theory of natural selection & evolution.
