Document Summary

Adaptation: allow organisms to meet recurring environmental challenges to their survival, thereby increasing their reproductive ability. Altruism: occurs when one individual helps another, but in so doing accrues some cost. Chromosomes: tightly coiled strands of deoxyribonucleic acid (dna) and protein that contain the genes. Concordance: the likelihood that two people share a particular characteristic. Evolution: a change over time in the frequency with which particular genes and the characteristics they produce occur within an interbreeding population. Genes: the biological units of heredity, located on the chromosomes. Genetic determinism: the view (sometimes erroneous) that genes have invariant and unavoidable effects; the idea that genes are destiny. Natural selection: the evolutionary process through which characteristics that increase the likelihood of survival are preserved in the gene pool and thereby become more common in a species over time. Reaction range: the genetically influenced upper and lower limits.
