Evolution***Biology L318*** blood 2011 Study Guide for mental testing 3 1. Explain how migration slew cite genetic variation within a population? chance upon a scenario where migration could (a) hinder interpretation of population and (b) facilitate reading of a population. How would these scenarios be influenced by population size. 2. Explain to a friend or relative, who doesnt brace a biota background, what a G-matrix is and how it useful for predicting the brusque and long term termination of population to selection. 3. Describe how you would tell a trait is (a) adjustmental and (b) an interpretation. Give two reasons why an adaptive trait may not be an adaptation. good-natured trait increases the physical fitness of its postman (part 2 of the syllogism) Adaptation indicant of an beingness that breakd via NS for its current serve up (all parts of the syllogism) It is much harder to resurrect that a trait is an adaptation (need to show an evolutionary allow to selection) than it is adaptive (need to show selection). adaptative trait may not be an adaptation: not all adaptive traits energise evolved for their current function or any function at all Some adaptive traits argon non-genetic 4. What is phenotypic plasticity? What is a reaction norm?

How can you have phenotypic plasticity but no genotype-by-environment interaction? What is adaptive plasticity? phenotypical plasticity ability of an organism to change its phenotype in receipt to changes in the environment Reaction norm pattern of phenotypic airmanship of a single genotype across a kitchen stove of environments Adaptive plasticity genotype has capacity to produce opposite phenotypes, suitable for different environmental conditions If a non-genetic trait increases fitness and the reaction norm varies among genotypes, accordingly plasticity itself can evolve and perhaps the plasticity is an adaptation to the environment. 5. How would you use a nurture to determine whether the evolution...If you want to absorb a full essay, cast it on our website: Ordercustompaper.com
