Unformatted text preview: 1. Be able to w in class Unit 17: 7. Be able to identify what inevitably happens to populations that undergo prolonged J-shaped growth. a. Will overshoot carrying capacity and start to crash/ die off Unit 16: 1. Be able to calculate allele frequencies for a given gene pair, given the proportion of dominant and recessive alleles within a population, for that gene pair a. Number of allele divided by total number of that same letter. A=10 a=5 A= 10/15 2. Using complete sentences, be able to describe the five conditions that must be met for a population to undergo no change in the frequency of genes in its gene pool (The conditions needed for a population to achieve Hardy-Weinberg equilibrium) a. There must be no random events that differentially eliminate alleles b. There must be no migration in or out of the population c. There must be no reproductive or survival advantage to any gene/genotype d. All mating must occur at random e. Mutations cannot occur 3. Be able to definem using complete sentences, or identify the terms: gene pool, allele frequency, genetic diversity, genetic drift, gene flow, environmental selection, and mutation. a. Gene Pool: All of the inheritable alleles found within a given population b. Allele Frequency: Numeric rate at which a gene or allele occurs in a gene pool relative to the other alleles/genes in its gene pair. c. Genetic Diversity: The Variety of genes and genotypes in a gene pool d. Genetic Drift: Changes in gene/allele frequency owing to random factors e. Gene Flow: Movement of genes into or out of population resulting from migration f. Environmental Selection: Conditions of habitat create differential survival and replication of specific alleles. g. Mutation: An alteration to the nucleotide sequence of a gene. 4. Be able to write, using complete sentences, definitions for the terms: Evolution and evolutionary fitness a. Evolution: Changes in gene frequencies in populations over time b. Evolutionary Fitness: The ability of an organism or allele to survive and reproduce relative to other individuals or alleles within the population 5. Be able to differentiate between graphs representing the three different patterns of natural selection. (Directional, stabilizing, disruptive). Be able identify which is most likely to lead to speciation. a. Most likely to speciate: Disruptive...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
