O A. 0.49 O B. 0.70 O C.0.21 O D.0.42 QUESTION 2 A hypothetical population has two alleles for an “A" gene: A1 and A2. The allele frequencies of the population were determined to be 70% A1 and 30% A2. What is the expected (predicted) frequency of zygotes with the A1A2 genotype (2pq) if the population is at Hardy- Weinberg equilibrium? O A. 0.42 O B. 0.49 O C. 0.21 ODO 70

QUESTION 8 In a certain population of rabbits, 25 new rabbits are born and five move into the population from surrounding areas during a single year. However, 10 rabbits die, and five leave the population during the same time frame. What is the population change for that year? a. 30 b. No change c. 15 d. 25 e. 10
Question 5 A rather large population of organisms have 396 red-sided individuals and 557 tan-sided individuals. Assume that red is totally recessive. Please calculate the following: a) The allele frequencies of each allele b) The expected genotype frequencies. c) The number of heterozygous individuals that you would predict to be in this population. d) The expected phenotype frequencies. e) Conditions happen to be really good this year for breeding and next year there are 1,245 offspring. Assuming that all of the Hardy-Weinberg conditions are met, how many of these would you expect to be red-sided and how many tan-sided?
QUESTION 38 All of the following are true statements about the Hardy-Weinberg Equilibrium (HWE) principle, EXCEPT: a. HWE concludes that allele frequencies change over time. b. HWE principle assumes that all of the individuals in your population survive and reproduce equally. c. HWE concludes that if given the allele frequencies we can then accurately predict the genotype frequencies in the population. d. HWE principle assumes large, completely isolated populations.
QUESTION 26 When thinking about changes in allele frequencies over time, why do you care more about the effective population size rather than the census (total number of individuals) population size?
Question 1.You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A) The frequency of the "aa" genotype. B) The frequency of the "a" allele. C) frequency of the a allele, then the frequency is 60%. Question 6A very large population of randomly-mating laboratory mice contains 35% white mice. White colouring is caused by the double recessive genotype, "aa". Calculate allelic and genotypic frequencies for this population. Question 7After graduation, you and 19 of your closest friends (lets say altogether 10 males and 10 females) charter a plane to go on a round-the-world tour. Unfortunately, you all crash land (safely) on a deserted island. No one finds you and you start a new population totally isolated from the rest of the world. Two of your friends carry (i.e. are heterozygous for) the recessive cystic fibrosis allele (c). Assuming that the frequency of this allele does not change as…
QUESTION 42 Two different populations that have a high degree of gene flow are expected to… a. have similar levels of heterozygosity. b. have an FST close to 1. c. be completely isolated from each other. d. vary in allele frequency from one another.
QUESTION 8 Morphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. hypotheses that are testable and falsifiable. c. include control groups. d. exceedingly small sample sizes in each treatment group. e. experimental design that enables all full interpretation of differences.
Question 1.You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A) The frequency of the "aa" genotype. B) The frequency of the "a" allele. C) frequency of the a allele, then the frequency is 60%. D) The frequency of the "A" allele. E) frequency of A is by definition equal to p, so the answer is 40%. F) The frequencies of the genotypes "AA" and "Aa." G)The frequencies of the two possible phenotypes if "A" is completely dominant over "a."
Question 1. In total, how many plant populations were established in this experiment? In each of these populations, what was the initial frequency of each plant genotype? Question 2. Did evolution occur in the control populations? If so, what factor or factors may have caused evolution by natural selection in these populations? Explain your answer. Question 3. Did evolution occur in the populations exposed to the generalist herbivore? If so, what factor or factors may have caused evolution by natural selection in these populations? Explain your answer. Question 4. Compare results for the control and generalist herbivore treatments. Why do you think the experiment showed the results that it did? Plant Genotypes Suppose the researchers conduct another experiment to investigate whether a generalist herbivore can affect the natural selection of a plant species. They establish ten replicate populations of the plant and expose each to two experimental treatments: a control (no herbivore) and…
