You are studying a single-gene locus with two alleles in a population that is in Hardy–Weinberg equilibrium. Examination of a large sample of individuals from the population reveals there are six times as many heterozygotes as there are homozygote recessive individuals in this population. What is the frequency of the recessive allele? I don't know how to start his calculation with just a ratio of 6:1 I found an answer online that says the frequency of q=0.25 but the calculations (below) don't make sense to me. Please help me. What is the answer and how do I get to it? Hardy-Weinberg equation p2+2pq+q2=1 2pq/q2= 6/1 2p= 6q 2(1-p)= 6q 2-2q=6q q=0.25

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?
You observe a population of mice with 100 individuals. Brown fur is dominant to white fur. You count 80 brown mice and 20 white mice. What is the frequency of the dominant allele? (Answers rounded to 2 decimal places) You observe a population of mice with 100 individuals. Brown fur is dominant to white fur. You count 80 brown mice and 20 white mice. What is the frequency of the recessive allele? (Answers rounded to 2 decimal places) You observe a population of mice with 100 individuals. Brown fur is dominant to white fur. You count 80 brown mice and 20 white mice. What is the frequency of the homozygous dominant genotype? (Answers rounded to 2 decimal places) You observe a population of mice with 100 individuals. Brown fur is dominant to white fur. You count 80 brown mice and 20 white mice. What is the frequency of the homozygous recessive genotype?

In corn, yellow kernel color is governed by a dominant allele for white color, W, and by its recessive allele, w, . A random sample of 100 kernels from a population that is in equilibrium reveals that 9 are yellow and 91 are white. What are the frequencies of the yellow and white alleles in this population? What is the percentage of the heterozygotes?
If 80% of a population has a heterozy gous phenotype, and 16% of that population shows a recessive phenotype, is that population in Hardy - Weinberg equilibrium? In other words, does the population obey the rules of H - W? Perform a statistical analysis to determine your final answer.
Why can all the allele and genotype frequencies in a population be determined based on the number of recessive individuals in the population? Recessive individuals are represented by only q2 and dominant are represented by both 2pq and p2 Recessive individuals are represented by only p2 and dominant are represented by both 2pq and q2 Recessive individuals are represented by q and dominant are represented by p Recessive individuals are rare and thus less in numbers making it easier to calculate
A scientist is studying the population of Cape Fox over four generations to determine if the population is in Hardy-Weinberg Equilibrium. Use the data below to determine if this population is in Hardy-Weinberg Equilibrium. Frequency Type First Generation Second Generation Third Generation Fourth Generation Frequency of dominant alleles p=0.2p=0.2 p=0.25p=0.25 p=0.35p=0.35 p=0.2p=0.2 Frequency of recessive alleles q=0.8q=0.8 q=0.75q=0.75 q=0.65q=0.65 q=0.8 No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations. No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of dominant and recessive alleles are not equal. Yes, the population is in Hardy-Weinberg Equilibrium because the recessive allele is always greater than the dominant allele. Yes, the population is in Hardy-Weinberg Equilibrium because the fourth generation reverts back to the initial population levels.…
A scientist is studying a wild population of Japanese morning glories. It is easy to separate genotypes at a flower color locus by their phenotypes. Red individuals are homozygous for the R allele, yellow individuals are homozygous for the Y allele, and orange individuals are heterozygous. If the number of individuals with the following genotypes are: RR: 831 RY: 33 YY: 442 Is the population in Hardy Weinberg Equilibrium?
At least one of the discoverers of this genetic equilibrium (Hardy) developed this HW equation to show that the dominant allele will not always take over the population just because that allele has a dominant effect on the phenotype. What additional factor would have to be present to cause a dominant allele to increase to a frequency of 100%? Why is this factor essential for the dominant allele to “take over” the gene pool?
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?
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…
