BIO 182 exam 1 ASU Verified 2 colors - codominance 3 types of evolution - natural theistic- guided by God creation allele - a form of a gene that affects the way an organism looks/behaves artificial selection = - artificial breeding Assumptions of Natural Selection - organisms possess heritable differences certain organisms reproduce more than others blending - incomplete dominance Commonalities of species - reproduce and survive Cuvier - catastrophe Deductive - process in which one uses a general principle to predict a specific result diploid - when a cell contains 2 copies of each chromosome F2 - second generation genotype - the set of alleles that determine how an organism looks/behaves haploid - having a single set of unpaired chromosomes homologous - when 2 chromosomes contain the same genes How is a gene dominant - dominance results from biochemical processes involving enzymes associated with the gene How many species? - 3-5 million species Hutton and Lyell - geologists that said the earth was very old and had changed over time Inductive - one relates observations to arrive at a general conclusion- descriptive research Lamarck - inheritance of acquired characteristics Law of Segregation - Mendelian law stating that two alleles for each trait separate during meiosis mean anomaly - standard deviation Meiosis - diploid cell produces four haploid cells Mitosis - diploid produces 2 diploid cells non-polar - inside normal temperature - mean P1 - parental generation Requirements for experimentation - replicate observations control conditions randomize experimental units Sir Ronald Fisher - extended mendelian genetics to continuous traits additive effects Support for evolution: - natural selection, mutation, genetic drift temperature - datum temperature anomaly - deviation trait - a characteristic of an organism that varies genetically What led to Darwin's ideas - Galapagos finches, Lyell's geology and Malthus' population explosion Who evolves? - populations, not individuals
