- QUESTION 16 You are examining a beloved population of trillium in the backyard of your childhood home. You recall as a child that flowers were bright white. As you return to the population you note that many (but not all) of the flowers have a faint purple vertical stripe in the middle of each petal. List each of Darwin’s postulates and what must be true about your population if it has undergone evolution by natural selection for petal color.Question 3. There are 100 students in a class. Ninety-six did well in the course whereas four blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, if these traits involve dominant and recessive alleles, and if the four (4%) represent the frequency of the homozygous recessive condition, please calculate the following: A) The frequency of the recessive allele. B) The frequency of the dominant allele. C) The frequency of heterozygous individuals. Question 4 Within a population of butterflies, the colour brown (B) is dominant over the colour white (b). And, 40% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam, calculate the following: A) The percentage of butterflies in the population that are heterozygous. B) The frequency of homozygous dominant individuals. Question 5 A rather large population of organisms have 396 red-sided individuals…QUESTION 35 You are conducting a QTL analysis to better understand monkey flower color and shape. To begin you start with breeding a plant that produces a long white tubular flower with purple flat flower. You continue your breeding for many generations. Which of the following is something you most likely observe? a. Variation in flowers your F2 population far exceeded the parental generation characteristics. b. The flower phenotypes did not correlate between siblings and between parent-offspring pairs. c. The variation in phenotypes is greater in the F2 population compared to the F1 population. d. Through selective breeding of the F1 individuals you could not recover the parental generation.
- 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…Question 4 located the back of the brown is the notice the arbor vitae with itQUESTION 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.
- No, what I mean is still on no. 3. Which is the real answer. The step 1 or step 2 that you gave? And why it has a step?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."Monozygotic twins: Question 2 options: a) Share 50% of their genetic material and if one twin has schizophrenia the risk of the other having the illness if 40-50% b) Share 100% of their genetic material and if one twin has schizophrenia, the risk of the other having schizophrenia is 10-15% c) Share 100% of their genetic material and if one twin has schizophrenia, the risk of the other having schizophrenia is 40-50% d) Share 50% of their genetic material and if one twin has schizophrenia the risk of the other having the illness is 10-15%
- Question 2. A widow's peak hairline is a dominant trait and a straight hairline is a recessive trait. What will be the genotypes and phenotypes of children of a homozygous dominant parent and a heterozygous parent? a) Construct a Punnett Square - List gametes in the area with the dashed line and the genotypes of the offspring in the area with the sold line. b) Genotypes of Children-c) Phenotypes of children-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 23 Allele frequencies for eye color in a population of hippogriffs is p=0.73. How many individuals would you expect to be heterozygous in a population 150? (Assume HWE)
