Which of the following statements describes an example of genetic drift?a. Allele g for fat production increases in a small population because birds with more bodyfat have higher survivorship in a harsh winter.b. Random mutation increases the frequency of allele A in one population but not inanother.c. Allele R reaches a frequency of 1.0 because individuals with genotype rr are sterile.d. Allele m is lost when a virus kills all but a few individuals and just by chance, none ofthe survivors possess allele m.
Which of the following statements most accurately describes the effects of genetic drift on a population? a. Populations of the same size will follow the same evolutionary trajectory when evolving due to drift. b. Genetic drift has the potential to drive evolution in all populations. c. Allele frequencies in a population of infinite size will ultimately drift to fixation or loss. d. The loss of otters in California due to excessive hunting cause a founder effect.
If a population is in Hardy-Weinberg Equilibrium, where the dominant allele frequency is 0.2. Which of the following is true about the recessive allele frequency? Select the formula that you would use to find it. q = 1- 2pq q = p/2 q=1-p q = 0.05 then tell us if the statement "Populations in nature are ALWAYS in Hardy-Weinberg Equilibrium" is TRUE or FALSE
Considering the Hardy-Weinberg theorem’s assumptions, which of the following statements is NOT correct? (Recall that there are certain assumptions that must be true in order for the Hardy-Weinberg theorem to accurately predict genotype ratios in the next generation.)a) The population must be very large so there random genetic drift will not occur.b) No natural selection can occur.c) Mating must be random.d) Individuals must migrate into and out of the population so that gene flow will occur.e) Mutations must not occur.
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.
A population consist of 7 mice. For the coat trait, there are only two alleles: brown B and white (b). BB and Bb mice are brown; bb mice are white. In the population's gene pool, there are 7 white alleles(b). a) what is the frequency of the brown allel in the population? b) what do you predict the frequency of the bb genotype will be in the next generation if no evolution takes place in the population?
A recessive deadly allele is currently at a frequency of 0.20 in a randomly mating population. What is the expected frequency of this allele after one generation of natural selection? At the equilibrium?
n the 1960s, a population of squirrels (Sciurus carolensis) was being studied in Alabama and the coat color of the squirrels was found to range from the more common gray color (dominant) to the less common red color (recessive). When they sampled an area, they found 536 gray squirrels and 64 red squirrels. Assume that the population is at Hardy-Weinberg equilibrium. 1B. What is the frequency of the homozygous recessive individuals?(Put your answer here rounded to the nearest hundredth)
According to the Hardy-Weinberg Equilibrium (p2 + 2pq + q2 = 1, within 5% variation of 1) which of the genes in the following three populations is actively undergoing evolution? population 1: AA = 80%; Aa = 10%; aa = 10% population 2: AA = 55%; Aa = 35%; aa = 10% population 3: AA = 25%; Aa = 50%; aa = 25% the gene in populations 1 and 3 are undergoing evolution the gene in populations 1, 2, and 3 are undergoing evolution the gene only in population 1 is undergoing evolution the gene in none of the populations are undergoing evolution
Which of the following populations is not in Hardy-Weinberg equilibrium? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a. A population with 23 homozygous recessive individuals (yy), 7 homozygous dominant individuals (YY), and 4 heterozygous individuals (Yy) b. A population that receives new individuals from a normally distant population. c. q + p = 1 d. A population in which the allele frequencies do not change over time
A species of fox may be brown (the dominant phenotype) or white (the recessive phenotype). Brown foxes have the genotype BB or Bb. White foxes have the genotype bb. The frequency in a population of foxes of the BB genotype is 0.27. A. How can we test if this population is operating under Hardy-Weinberg Equilibrium? B. Assuming that this population is operating under HWE, calculate the following: What is the frequency of the B allele in this population? What is the frequency of the b allele in this population? What is the frequency of heterozygous foxes in this population?
Which of the following statements is FALSE? Select one: a. Genetic drift is more likely to occur in a small population. b. Random mating occurs when individuals pair by chance. c. The dominant allele is always the most common allele in the gene pool. d. Evolution can be detected by noting a deviation from a Hardy–Weinberg equilibrium of allele frequencies in the gene pool of a population.
