Miguel says that the Hardy–Weinberg law is only theoretical, of nopractical value, and totally worthless because populations will neverbe large, randomly mating for all traits, and free from all evolutionaryforces. Thus, he asserts that populations will never be in Hardy–Weinberg equilibrium. Barbara says she knows the Hardy–Weinberglaw is important. Who is correct and why?

You are given the frequencies of all three genotypes (AA, Aa, aa) in a population, and all three are non-zero. Under what conditions can you determine allele frequencies? Only if the population is in Hardy-Weinberg equilibrium Only if the population is NOT in Hardy-Weinberg equilibrium Always: It doesn't matter whether or not the population is in Hardy-Weinberg equilibrium
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? Drawing on your newly acquired understanding of the HardyWeinberg equilibrium law, point out why the following statement is erroneous: Because most of the people in Sweden have blond hair and blue eyes, the genes for blond hair and blue eyes must be dominant in that population.
You are given the frequencies of both alleles (A and a) in a population, and both are non-zero. Under what conditions can you determine genotype frequencies? Only if the population is in Hardy-Weinberg equilibrium Only if the population is NOT in Hardy-Weinberg equilibrium Always: It doesn't matter whether or not the population is in Hardy-Weinberg equilibrium
Hitchhiker's thumb is an autosomal recessive trait determined by a single gene with two alleles, H and h. Suppose the allele frequencies in a population are f(H) = 0.8 and f(h) = 0.2. Which combination(s) of genotype frequencies is/are possible in this population if it is in Hardy- Weinberg equilibrium? List all that are possible. O f(HH) = 0.64, f(Hh) = 0.32, f(hh) = 0.04 O f(HH) = 0.6, f(Hh) = 0.2, f(hh) = 0.2 %3D f(HH) = 0.6, f(Hh) = 0.4, f(hh) = 0 %3D f(HH) = 0.7, f(Hh) = 0.2, f(hh) = 0.1 O f(HH) = 0.8, f(Hh) = 0, f(hh) = 0.2
In mice, black fur (W) is dominant over white fur (w). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, 167 mice out of 225 have white fur. Calculate the number of mice that are heterozygous dominant for the fur colour gene in the population. Show all work. Express your answer rounded to the nearest whole number:
Hitchhikers thumb is a recessive trait. We'll use: H=non-hitchhikers thumb allele and h=hitchhikers thumb allele. Assumer people without hitchhiker's thumbs find people with hitchhiker's thumbs sexy and vice versa - (the Vive la diference theory-haha). If this preference leads to non-random mating in a population that starts out in Hardy-Weinberg equilibrium, and no evolutionary forces act on the population, what will happen to the frequency of people with hitchhiker's thumbs in the next generation? Hint: this is a bit tricky to figure out. Consider all the possible genotypes and who each would mate with if they only mate with individuals with different phenotypes. Then think what that would do to the phenotype frequency over time. O The frequency of people with hitchhikers thumbs will decrease in the next generation. O The frequency of people with hitchhikers thumbs will increase in the next generation. O It will stay the same. (Since there are no forces.)
In a given population on a distant planet, there are 20 red, 25 orange, and 15 yellow creatures. Use Hardy-Weinberg equations and a chi square analysis to determine whether or not this population is in Hardy-Weinberg equilibrium. Show all work. Be sure to state a null hypothesis and explain your conclusion.
When we find a population whose allele frequencies are not in Hardy–Weinberg equilibrium, what can and can’t we conclude about that population?
In smurfs, blue tails and red tails are codominant to white tails (this is similar to blood type in humans). In a population of 200 smurfs, 6 have white tails, 93 have blue tails, 51 have red tails, and 50 have purple tails. Papa smurf has learned that the frequency of the blue tail allele is 0.53. Is this population in Hardy-Weinberg Equilibrium? Be sure to do a Chi-square test and show your work.
It is a common but mistaken belief that because some allele are dominant and others are recessive, the dominants will eventually replace all the recessives in a population. How does the Hardy-Weinberg equilibrium refute this notion?
Dimples are a dominant phenotype, determined by one gene with two alleles (D, d). From data obtained from a sample of 400 individuals, 96 of the individuals had dimples. What are the frequencies of the two alleles in this population assuming Hardy-Weinberg equilibrium?
