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?

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?
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?
American cat breeders are trying to establish a new breeed of cat with unusual, curled-back ears, to be known as the "curl cat." Suppose you found a curl cat and wanted to secretly start your own population. How would you determine whether the curl allele is dominant or recessive? How would you establish and maintain a true breeding population based on whether the allele is dominant or recessive?
How Can We Measure Allele Frequencies in Populations? In a population where the females have the allelic frequencies A = 0.35 and a = 0.65 and the frequencies for males are A = 0.1 and a = 0.9, how many generations will it take to reach HardyWeinberg equilibrium for both the allelic and the genotypic frequencies? Assume random mating and show the allelic and genotypic frequencies for each generation.
How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?
Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If natural selection occurs in this population, what would you expect to see if you returned in 100 mouse generations? Describe what you'd see in terms of fur colors in the population. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If mutations occur in this population, what could you see if you returned in 100 mouse generations, that would tell you mutations had occurred? Describe what you'd see in terms of fur colors in the population, and how it would be different from what you'd see in #2.
You are studying a population of penguins in Antarctica. Your DNA analysis of this population reveals that for the feather color pattern gene, 35 individuals are homozygous dominant, 35 individuals are heterozygous, and 30 individuals are homozygous recessive. After observing this population for several years, you repeat your DNA study and find that the current generation of penguins has 15 individuals that are homozygous dominant, 10 individuals that are heterozygous, and 75 individuals that are homozygous recessive. Which of the following hypotheses for this data would be supported by this data based on your understanding of Hardy-Weinberg equilibrium? This population of penguins is maintaining Hardy-Weinberg equilibrium due to its large population size. The penguins are randomly choosing mates, which has led to Hardy-Weinberg equilibrium. The penguins are very isolated, which is preventing gene flow from affecting Hardy-Weinberg equilibrium. The recessive phenotype in…
How can negative traits that don't show up until old age continue in populations? (Why aren't they eliminated through natural selection?) As part of your answer, provide an example.
A hypothetical population of 10,000 humans has 6848 individuals with the blood type AA, 2846 individuals with blood type AB, and 306 individuals with the blood type BB. What is the frequency of each genotype in this population? What is the frequency of the A allele? What is the frequency of the B allele? If the next generation contained 25,000 individuals, how many individuals would have blood type BB, assuming the population is in Hardy-Weinberg equilibrium?
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
What is neutral evolution? A. Neutral evolution does not exist. B. When certain genes are present or absent in populations due to natural selection (they are advantageous or disadvantageous). C. When certain genes are present or absent in populations regardless of selection (they are not advantageous or disadvantageous). D. When certain genes are present or absent in populations due to sexual selection (they are selected for by the opposite sex).
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…
