You survey a population of minnows in Hardy-Weinberg equilibrium and find that there are three different genotypes; Red, Purple, and Blue fins. The genotypes for Red (RR), Purple (Rr), and Blue (rr) fins have different survival rates at 0.7, 0.8, and 0.5, respectively. The size of the population does not decrease from generation to generation and all individuals lost to selection are replaced by new individuals being born. If the population starts with 30 Red, 30 Purple, and 40 Blue fins, what is the expected number of individuals of each genotype in the next generation (round to nearest whole individual)? Clearly show each step of your work.

Your study of the natural hamster population yields observed genotypic frequencies of 60% AA, 20% Aa and 20% aa. Compare the observed genotypic frequencies with the expected frequencies for a population in Hardy-Weinberg equilibrium. Genotype Observed Expected AA 0.60 0.30 Aa 0.20 0.50 aa 0.20 0.20 Is this population in Hardy-Weinberg equilibrium? Is it likely this population is experiencing evolution as defined by changes in allele frequencies between generations?
Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations. Fitness CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0 Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Which of the following statements is true based on the information you have on these populations?
Imagine a remote island inhabited by a population of lizards. To determine if this population is in Hardy-Weinberg equilibrium for gene X, which of the following conditions must be met? The lizard population should be at least 100 individuals and close to other large populations to avoid genetic drift. No selection, meaning that all individuals have an equal chance of survival and reproduction No gene flow due to migration between the island and other lizard populations Random mating among lizards without any preference to gene X No measurably significant mutations occurring in the lizard population at gene X
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 this population is in Hardy-Weinberg Equilibrium, what percentage of the bugs would we expect to be white? Calculate the genotype frequencies of the 2nd generation is a hint.
An allele A is present in a population at a frequency of 0.29, and there is only one other allele at the same locus. Fitness is associated with variation at the locus carrying the A allele such that there is a selection coefficient s equal to 0.03. What would you expect the frequency of the A allele to be after one generation of natural selection. Compute your result up to four decimal places.
The vgll3 locus is responsible for the age at which salmon mature. The vgll3 L allele causes salmon to mature earlier. This is the data on the frequency of the vgll3 L allele collected from Alaskan salmon over the course of 30 years. Which of the following describes whether this population is at Hardy-Weinberg equilibrium, and why? A - This population is not at Hardy-Weinberg equilibrium because there is evidence of selection against earlier maturing salmon. B - This population is at Hardy-Weinberg equilibrium because there is no overall trend in allele frequency over the study period. C - This population is not at Hardy-Weinberg equilibrium because there is evidence of the introduction of new mutations causing salmon to mature earlier. D - This population is at Hardy-Weinberg equilibrium because including salmon from six rivers ensures a large and genetically stable population.
Consider a gene with two alleles, C and M. The table below describes fitness for different genotypes in two populations. Fitness CC CM MM Population 1 1.0 1.0 0.6 Population 2 0.9 0.9 1.0 Assume that both populations begin with frequencies of 0.5 for each allele, population size is infinite, and there is no migration between populations. Would you predict that either allele would become fixed in either population?
Twenty snakes with the Aa genotype migrated to a population of 80 snakes of the same species with the AA genotype to form a new population. Assuming that the new population is now "ideal" (under genetic equilibrium) and remains "ideal" for future generations, what percentage of snakes will have the Aa genotype in the next generation? What is the frequency of the a allele in the population after three generations? Show your calculation.
Assume that the frequency of gene B in a hypothetical population Is 0.63, that there are only two alleles (B and b) of the gee in the population, that allele B is dominant over allele b, that neither allele has a selective advantage over the other, and that the population is at equilibrium with regard to this particular gene. What is the expected frequency of the b allele in this population, based upon the Hardy-Weinberg formula? A. 0.29 B. 0.14 C.0.21 D.0.40 E.0.37
Consider a population of 150 mice on an island, with allele frequencies B = 0.20 for brown coat colour, and b = 0.80 for white coat colour. Brown (B) is dominant to white (b) and the population is in Hardy-Weinberg equilibrium. Twenty-five homozygous brown mice from the mainland float to the island on an uprooted tree after a storm. What are the genotype frequencies before migration? What are the allele frequencies after migration? Now, suppose the twenty-five brown mice float away again on another tree without breeding, and the island is back to its original state. Allele frequencies on the island are back to B = 0.20, b = 0.80. On the continent, there is a large population of many thousands of mice, with allele frequencies B = 0.80, b = 0.20. One year, human ships begin moving back and forth between the island and the continent, and occasionally a mouse comes along for the ride, and stays and breeds. Equal numbers of mice ride in each direction. The shipping trade continues…
A survey of a butterfly population showed that most individuals have blue wing spots. On occasion, some rare yellow-spotted individuals can be found as well. Further genetic studies showed that the colors are controlled by a single gene, with C dominant over c. Also, out of 300 samples, only 27 are yellow and the rest blue. Assuming that this population is in Hardy-Weinberg equilibrium, what is the allele frequency for the C allele? -0.3 -0.4 -0.6 -0.7 -0.9
The following conditions are required for Hardy-Weinberg equilibrium: Mutation, non-random mating, migration and directional selection No migration a no selection No mutation of alleles, random mating and migration Non-random mating, differential frequency selection and no mutations Small population, no mutation and genetic drift
