Cancer : uncontrolled growth and division of cells, failure in regeneration of cell cycle
Carcinogens : substances known to cause cancer
Genetic Recombination : new combinations of genes produced by crossing over
Polyploidy : extra set of chromosomes in an organism
Nondisjunction : when sister chromatids fail to separate completely
Mutation : a permanent change in a cells DNA
Genetic Engineering : technology that allows manipulation of DNA
Mutagen : chemical substance that causes mutations
Cloning : process in which large numbers of identical recombinant DNA molecules are produced
Transgenetic Organisms : genetically engineered by inserting a gene from another organism
Haplotypes : regions of linked variations in the human genome
Pharmacogenomics : study of how genetic inheritance affects bodies response to drugs
Gene Therapy : a technique aimed at correcting mutated genes that cause human disease
Hardy Weinberg Principle : states: allelic frequencies in populations consist unless altered
Genetic drift : change in allelic frequencies in a population due to change
Founder Effect : when small sample of population is separate from the rest of the population
Bottleneck : when population declines very low then rebounds
Directional Selection : extreme version of trait that makes an organism more fit to live
Disruptive Selection : process that splits population into 2
Sexual Selection : when males and females differ significantly in appearance
Prezygotic Isolation mechanisms : operates before fertilization
Postzygotic Isolation Mechanisms : operates after fertilization
Allopatric Separation : physical barrier that divides a population
Sympatic Separation :species evolve without physical barrier
Adaptive radiation : diversification of a species into multiple species over a short period of time
Gradualism : theory that evolution occurs in small gradual steps
Punctuated Equilibrium : theory that attempts to explain abrupt transitions in fossil record
