17a. Assuming that both types of pom-poms are present in the population, what do you think would happen to the pom-pom population if the black forest experienced a prolonged drought so all the trees died and the habitat became red grassland? 17b. Next, think about an alternative scenario. Suppose that natural selection over many generations had eliminated all the red pom-poms in the black forest habitat so only black pom- poms survived. After that, a prolonged drought resulted in this habitat turning into a red grassland. Would natural selection for pom-pom color occur? Why or why not? 17c. The above scenarios are showing that in order for natural selection to occur must exist within a trait.

The original source of new alleles, upon which selection operates,is mutation, a random event that occurs without regard to selectionalvalue in the organism. Although many model organismshave been used to study mutational events in populations, someinvestigators have developed abiotic molecular models. Soll et al.(2006. Genetics 175:267–275) examined one such model to studythe relationship between both deleterious and advantageousmutations and population size in a ligase molecule composed ofRNA (a ribozyme). Soll found that the smaller the population ofmolecules, the more likely it was that not only deleterious mutationsbut also advantageous mutations would disappear. Whywould population size influence the survival of both types ofmutations (deleterious and advantageous) in populations?
Three basic predictions underlie genetic drift in populations: (1) As long as the population size is finite,some level of genetic drift will occur; thus, withoutnew mutations, all variation will drift either to fixationor to loss. (2) Drift happens faster in small populationsthan in large populations. (3) The probability that anallele is fixed (goes to a frequency of 1.0) is equal toits initial frequency (p) in the population, while itsprobability of loss from the population due to drift isequal to 1 − p. Given these three predictions:a. What is the allele frequency of a new autosomalmutation immediately after it occurs in a diploidpopulation of size N = 100,000?b. What is the allele frequency of a new autosomalmutation immediately after it occurs in a diploidpopulation of size N = 10?c. In which population does the new mutation have ahigher probability of going to fixation by chancewith genetic drift?
Pikas are small mammals that live at high elevations on the talus slopesof mountains. Most populations located on mountaintops in Coloradoand Montana in North America are isolated from one another: the pikasdon’t occupy the low-elevation habitats that separate the mountaintopsand don’t venture far from the talus slopes. Thus, there is little gene flowbetween populations. Furthermore, each population is small in size andwas founded by a small number of pikas.A group of population geneticists proposes to study the amount ofgenetic variation in a series of pika populations and to compare theallelic frequencies in different populations. On the basis of the biologyand distribution of pikas, predict what the population geneticists willfind concerning the within- and between-population genetic variation.
The elaborate tail of the peacock (Pavo cristatus) is approximately 120 cm to 150 cm long, while the tail ofthe peahen is quite short. The long tail reduces the male bird’s ability to maneuver and fly and makes him moreconspicuous to predators. Suggest at least one reason why this cumbersome structure has not been eliminatedby natural selection.
In a certain population of frogs, 120 are green, 60 arebrownish green, and 20 are brown. The allele forbrown is denoted GB, while that for green is GG, andthese two alleles are incompletely dominant.a. What are the genotype frequencies in thepopulation?b. What are the allele frequencies of GBand GG inthis population?c. What are the expected frequencies of the genotypes if the population is at Hardy-Weinbergequilibrium?
What is the role of variation in evolution. If heterozygosity is reduced, what happens to the potential for evolution?. The phenotype and genotype bof a population is die to a mosaic of random and directed processes, some of them have to do with history ;some are related to adaptation, etc. As completely as possible, discuss the role of chance and direction in evolution and in determining the phenotype of a population
Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?
Natural selection tends to work toward genetic unity;the genotypes that are most fit produce the mostoffspring and increase the frequency of adaptive allelesin the population. Yet there remains a great deal ofvariability within the populations of species. Describethe factors that contribute to this genetic variability. Provide the link of references
The evolution of a qualitative trait in reponse to natural selection is described by the following equation, R=h2 S a) What is h2 and what does it measure? b) Describe a study that would allow you to estimate h2 for a real population
Suppose that recessive deleterious allele is found to be much less common than its predicted equilibrium frequency, based on the selection coefficient and mutation rate measured in modern populations. Which of the following is the best explanation for this? Note that, when selection or mutation rates change, it may take hundred of generations for population to reach its new equilibrium. A. Selection against the allele was weaker in the past than today B. Mutation rates were higher in the past C. Heterozygote advantage in some environments D. Increases lifespans have made the allele more deleterious now than it was in the Please answer asap and in short and content should not be palgarised please
You are asked to assess whether a population of endangered salamanders can adapt to warming climate in their preferred habitat. The salamanders vary at a locus that determines adaptation to temperature, and the warming climate creates selection favoring one of two alleles at that locus. Drawing on what you know about natural selection and genetic drift, what information would you need to know about the salamanders to determine whether the allele that improves their adaptation to warmer climates will become fixed in the population? Strictly no plagiarism.
Let’s say that a large ancestral population of really cool organisms is subdivided, by a geological cataclysm, into a large number of isolated, ideal populations, each of size 100. Suppose we’re interested in an autosomal locus with two alleles, A and a, with p = the frequency of A = 0.75 in the ancestral population, as well as in each newly isolated population. Assume that genetic drift is the only evolutionary force operating. a) What is the average allele frequency of A in the populations after 5, 10, and 100 generations? b) What allele frequencies of A do you expect to find within each population at equilibrium, and what percentage of the populations will have each specific allele frequency? (recall various simulations we did/could do of genetic drift in several populations) c) What is the average Inbreeding Coefficient (or Fixation Index) F for each population after 20 generations? Assume F = 0 for all individuals in the ancestral population. d) Redo (c), assuming an initial…
