You measure the effects of a single allele (Y) on fitness in two populations of spiders, Population A and Population B. Population A lives near agricultural fields where the pesticide is sprayed regularly. The average excess of fitness of the Y allele (aY) in Population A is 1.0, and the average fitness of the population (w) is 1.0. Population B lives in a remote forest and is never exposed to pesticides. The average excess of fitness of the Y allele (aY) in Population B is 1.8 and the average fitness of the population (w) is 1.0. a) In which mosquito population is the frequency of the Y allele going to change faster? (A,B) b) What do you predict will happen to the frequency of the Y allele (pY) in Population B (increase, decrease,stay the same)

A population of 1000 beetles has 600 individuals that have genotype QQ, 100 individuals that have genotype Qq, and 300 individuals that have genotype qq. a) Calculate f(Q) and f(q) for this population. Show your work and don’t assume HWE. b) Calculate f(QQ), f(Qq), and f(qq) for this population. Show your work and don’t assume HWE. c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work. d) Does this population appear to be at Hardy-Weinberg equilibrium? Why or why not? (Although answering this question rigorously would require a statistical test, you don’t need to do that here.).
If there are 12 rock pocket mice with dark fur and 4 with light-colored fur in a population, what is the value of q? Remember that light-colored fur is recessive. If the frequency of p in a population is 60% (0.6), what is the frequency of q? In a population of 1000 rock pocket mice, 360 have dark-colored fur. The others have light-colored fur. If the population is in Hardy-Weinberg equilibrium, what percentage of mice in the population are homozygous dominant dark-colored mice?
If after studying a population for a trait determined by a single pair of alleles you find that the population is not in equilibrium, what possible reasons might explain the lack of equilibrium
if a population of jumping spiders consists of 40 females and 40 males, what is the effective population size? Give the appropriate equation and show your work. Will genetic drift be an important evolutionary force in this population? Why or why not? If your answer is "yes", what does genetic drift do to allele frequencies? If your answer is "no", name two forces other than genetic drift that might be important in determining allele frequencies. asap
In a hypothetical bug population, color is determined by a single gene and black is dominant over white. The frequency of the black allele is 0.1. If the population is in Hardy-Weinberg Equilibrium, what percentage of the bugs would you expect to be white? Please show your work.
You observe some bark beetles with different feeding behaviors. You find that the behavioral phenotypes you observed are closely associated with the following genotypes. genotype phenotype number observed BB feeds under bark 60 Bb feeds on top of bark 24 bb feeds on leaves 16 a) What are the allele frequencies and the expected number (out of 100 beetles) of genotypes? b) Calculate the Chi-Squared value (c2). Then look up the p-value using this Chi-squared calculator: https://www.mathsisfun.com/data//chi-square-calculator.html Enter “1” for Degrees of Freedom. (There are 3 genotype categories, but only 1 DF because they are not fully independent—calculated from just 2 allele frequencies). The p-value is the probability that you would see the deviance you observed by chance, assuming the null hypothesis is true). Report both values. Is the population in H-W equilibrium? c) If you answered “No” to b): Provide at least three biologically…
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 green frogs would you expect to observe? (Remember to multiply the expected frequency by the number of frogs in the population.)
Consider a hypothetical beetle whose back abdomen pattern is determined by two alleles A1 and A2. Beetles that are homozygous for the 'A1' allele have solid coloring, beetles that are heterozygous (A1A2) are spotted, and beetles that are homozygous for the A2 allele are striped. You find a population of 100 of these beetles and count each phenotype (shown below). TRUE or FALSE: this population is in Hardy-Weinberg equilibrium? What is the predicted frequency of spotted beetle? Solid Beetles = 49 Spotted Beetles = 35 Striped Beetles = 16 asap please
