You set up two populations of fruit flies (Drosophila) in the lab in large enclosures. One population is maintained in a high food condition in which food is constantly abundant and uniformly distributed, whereas the second population is maintained in a low food condition is which food is scarce and randomly distributed. You allow the populations to live and breed in the enclosures for 500 generations. Which of the following can you correctly predict to occur? a. the “sitter” allele (forS) will increase in the high food population. b. the “rover” allele (forR) will increase in the high food population. c. flies in the low food population will have higher levels of PKG compared to flies in the high food population. d. flies in the high food population will have higher levels of PKG compared to flies in the low food population. e. a and c f. b and d g. none of these

Suppose that you are examining a population of 100 cats. You are interested in the gene for hair length. This gene has two alternate alleles: short and long hair. If you pick any one cat from the population, how many alleles for hair length would it have? A-1 B-2 C-100 D-200 Suppose every cat in this population could somehow remove its alleles for hair length and dump them into a container. If you were to count the alleles for hair length contributed by all these cats, how many alleles would the entire population of cats have? (In other words, how many alleles would be in the container?) E-100 F-200 A dominant allele codes for short hair in cats. If a particular cat has long hair, what must be the genotype of that cat? A-Heterozygous B-Homozygous Dominant C-Heterozygous Recessive
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?
You discover that there are 4 alleles for the “w” gene that determines wing shape in flies. Is this a violation of Hardy-Weinberg model? Group of answer choices Not if one of the alleles is present only in females. Not if the trait is determined by sexual selection. Not if all four alleles are present in the population. Yes, because Hardy-Weinberg can only be applied to genes with 2 alleles. None of the answers shown are correct.
In experiment of genetic drift, suppose you have a population of 300 butterflies. if the population experiences a net growth of 12% in the following year, how many butterflies do you have? Now supposed you have 300 eggs, but only 70% of those eggs become caterpillars, and only 80% of the caterpillars become adult butterflies. How many butterflies do you have? (For simplicity, assume that all butterflies survive to the next year in this example.)
If gene A/a is not in Hardy-Weinberg equilibrium due to natural selection such that individuals with the genotype AA have a fitness value of 1.0, heterozygotes have only slightly reduced fitness at 0.9, and individuals with the genotype aa have a fitness value of 0.6, what kind of change in allele frequency would you expect to see over time assuming you start with equal frequencies of the 2 alleles?
In a certain population of mice, a single gene controls fur color. There are two possible alleles: B, which leads to a black fur, and W, which leads to white fur. Individuals with the genotype BB will have a black fur, individuals with the genotype WW will have white fur, and individuals with the genotype BW will have gray fur. Scientists recorded the fur color of 1,000 mice from the population. They found that 200 mice have black fur, 400 have gray fur, and 400 have white fur. Ten years later, the measurements are repeated. Again, they recorded the fur color of 1,000 mice. They found that 400 have black fur, 400 have gray fur, and 200 have white fur. Part A: Show the Hardy-Weinberg calculations for the beginning and ending populations. Include the values for the equation as well as the p and q values. Show your work. Part B: Use the Hardy-Weinberg calculation to explain if this population is evolving or not. Then propose a hypothesis about the environment of these mice that would lead…
If a population were to remain in Hardy Weinberg Equilibrium, which of the following is correct? If a population were to remain in Hardy Weinberg Equilibrium, which of the following is correct? The population can still grow, but the allele frequencies will remain constant in each generation The population can still grow, but the allele frequencies may change with each generation Since it is at equilibrium, the population cannot grow
10,000 individuals are sampled from a population and are found to display one of three blood types: AA with 6800 individuals, AB with 2800 individuals and type BB with 400 individuals. a) What is the frequency of each genotype in the population? b) What is the frequency of the A allele? c) What is the frequency of the B allele? d) If the next generation contains 25,000 individuals, how many would have blood type BB, assuming the population is in Hardy-Weinberg Equilibrium?
you (should have) learned that selection alone cannot purge a population of the very last copy of a deleterious allele. If selection is unable to do so, which of the remaining mechanisms (of the five Hardy-Weinberg) assumptions is MOST LIKELY to do so? Justify your answer. That is, why is the mechanism you picked the most likely to get rid of that last copy of a harmful allele?
You are studying the genetics of an enzyme found in fish. In the population in one lake, the value of pis 0.13 and the value of q is 0.87. Which percentage of the population would be predicted to have heterozygous genotypes for this gene if the population is in Hardy-Weinberg equilibrium?
In a population of deer mice, the allele for white hair is recessive and the allele for brown hair is dominant. If the population consists of 500 individuals and the frequency of homozygous brown mice is 49%, what is the frequency of the recessive allele? Assume the population is in Hardy-Weinberg equilibrium.
In a certain population of frogs, 120 are green, 60 are brownish-green, and 20 are brown. The allele for brown is denoted GB, and the allele for green is designated GG. These two alleles are incompletely dominant to each other. If this population were in Hardy-Weinberg equilibrium, how many brownish-green frogs would you expect to observe?
