LIFESCI 1 Chapter Notes - Chapter 21: Mutation, Allele Frequency, Genotype Frequency
Document Summary
Species: a group of individuals that can exchange genetic material through interbreeding to produce fertile offspring. Gene pool: all the alleles present in all individuals in a population or species. Population: all the individuals of a given species that live and reproduce in a particular place; one of several interbreeding groups of organisms of the same species living in the same geographical area. Somatic mutation: a mutation that occurs in somatic cells. Germ-line mutation: a mutation that occurs in eggs and sperm or in the cells that give rise to these reproductive cells and therefore is passed on to the next generation. Neutral mutations: genetic changes that have no effect or negligible effects on the organism, or whose effects are not associated with differences in survival or reproduction. Deleterious mutations: genetic changes that are harmful to an organism. Advantageous mutations: genetic changes that improve their carriers" chances of survival or reproduction.
