Microevolution Study guides, Class notes & Summaries

BIO-107 test 1 Questions and Answers 100% Solved Microevolution Evolutionary change below the species level; Change in allele frequencies over generations. It is called micro evolution because it focuses on evolution in population, which is the smallest scale. (individuals do not evolve.) 3 mechanisms that cause allele change Natural seletion, genetic drift( chance events that alter allele frequencies), and gene flow (the transfer of alleles between populations). Population is a group...

Species richness - correct answer the number of species in a given area Species evenness - correct answer the relative proportion of individuals within the different species in a given area Phylogeny - correct answer The evolutionary history of a species or group of related species Evolution - correct answer Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms. Microevolution - correct answer Evolution between the species lev...

Why is the scientific method bad? - Answer-It is oversimplified, it implies that an experiment can answer a research question. Science isn't linear. It implies science is an independent effort, no creativity or imagination, and it ignores technology and society What is a theory? - Answer-Theories are broad explanations. They are supported by lines o evidence, with no contradictory evidence. Therefore the evolutionary theory isn't just a "theory" Why don't community analysis and feedbac...

SCIN130 Chapter 15 Test Questions with Correct Answers Natural Selection - Answer-the process that results in adaptation of a population to the biotic and abiotic environments. Polygenic - Answer-controlled by more than one pair of alleles located at different gene loci Directional Selection - Answer-occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Example: resistance to antibiotics and pesticides Stabilizing Selection - Answer-Occurs wh...
