EVOLUTION FINAL EXAM | 57 questions and answers latest hybrid sterility isolation - Sterile hybrids genetic incompatibility` Two loci can show genetic incompatibilities T/F - True Dobzhansky-Muller incompatibility - Solves the problen of how genetic incmopatibilities can evolve between two populations Epistasis - When the effects of one gene are modified by one or more other genes. this is genetic incompatibility as well How is epistasis identified. - When the total effect on f...

species - evolutionarily independent population or group of populations synapomorphy - a trait that is found in certain groups of organisms and their common ancestor, but is missing in more distant ancestors; identifies monophyletic groups; homologous traits that can be identified at the genetic, developmental, or structural level biological species concept - reproductive isolation between populations (they don't breed and don't produce viable, fertile offspring) - reproductive isolation...

Why might Pasteur's experiment be inconclusive? - Answer The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - Answer To ensure that results were not achieved by random chance What is the definition of a replicate? - Answer Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession suggest?...

Spatial & Temporal Scale of Perception -Spacial Scale= space -Temporal Scale= time -i.e.: instincts & responses Impediments to Solving Environmental Problems -Spatial & Temporal Scales -Lack of education -Lack of scientific understanding -"cheap citizen" (doing harm & expecting others to fix it) Types of Errors -Type 1: Rejecting a null hypothesis when its true -Type 2: Accept a null but its false Null Hypothesis Statement of no trend, effect, or impact (Give...

BIOL 3040 STUDY GUIDE II, PART A Chapter 4 Synapomorphy: A character or trait that is shared by two or more taxonomic groups and is derived through evolution by a common ancestor. Homoplasy: Correspondence between parts or organs acquired as a result of parallel evolution or convergence. Homoplasy is analogous and can be due to convergent evolution 1. According to the tree below: a Species B is more closely related to species G than species A b Species B is equally related to specie...

The general lineage species concept - ANSWER-is the idea that species are metapopulations of organisms that exchange alleles frequently enough that they comprise the same gene pool and therefore the same evolutionary lineage. speciation - ANSWER-is the evolutionary process by which new species arise. Speciation causes one evolutionary lineage to split into two or more lineages (cladogenesis). An isolating barrier - ANSWER-refers to an aspect of the environment, genetics, behavior, physio...

Evolution notes discussing the 3 main species definitions, and models of speciation, including visual aids. Discusses mechanisms of speciation including pre and post zygotic barriers, and genetic drift.
