- When we find a population whose allele frequencies are not in Hardy–Weinberg equilibrium, what can and can’t we conclude about that population?The following data were obtained from a Ghanaian population of 152 people. Blood Type Number of Individuals M 61 MN 64 N 27 Calculate the frequencies of the M and N alleles in this population. What are the expected numbers of individuals of each genotypic class in this population? Assume Hardy-Weinberg conditions. Use the chi-squared test to determine if these data fit the Hardy-Weinberg equilibrium model. The degrees of freedom for this test should be 1. Why is this appropriate?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.
- A population has the following genotype frequencies AA=0.3844, Aa=0.4712, aa=0.1444. Assuming Hardy-Weinberg equilibrium, what are the allele frequencies in the population?the frequency of allele a is 0.45 for a population inhardy-Weinberg equilibrium. What are the expectedfrequencies of genotypes AA, Aa, and aa?A particular flower has two colors that are determined by one locus, where orange is dominant to blue. In a population of 1000 flower, 311 blue flowers are given. Assuming that the population is in Hardy-Weinberg equilibrium, fiind the number of heterozygotes.
- A population of dragons is as follows: 46 are green with genotype GG 106 are green with genotype Gg 56 are red with genotype gg Is this population in Hardy-Weinberg equilibrium? Assume 1 degree of freedom for your chi-square test.While supposing that two different alleles exist in a population that is in Hardy-Weinberg equlibrium. if p= frequecy of the "A" allele and q=frequency of the "a" allele, what is the expected frequency of "AA" individuals in the population? Possible answers: p,p+q, q, p^2, q^2, pq, 2pq, p^2+2pqIf you survey the genotype frequencies at locus E, which has alleles E (frequency =p) and e (frequency=q), and find that p2 + 2pq + q2 is much greater than 1, you can confidently conclude that Group of answer choices you made a math error the allele frequencies must also sum to greater than 1 the population is not at HWE with respect to locus E the population is not at HWE with respect to any loci
- A population with a heterozygosity value of 0.5 necessarily satisfies the Hardy-Weinberg equilibrium.A graduate student is studying a population of bluebonnets along aroadside. The plants in this population are genetically variable. Shecounts the seeds produced by each of 100 plants and measures the meanand variance of seed number. The variance is 20. Selecting one plant,the student takes cuttings from it and cultivates them in a greenhouse,eventually producing many genetically identical clones of the sameplant. She then transplants these clones into the roadside population,allows them to grow for one year, and then counts the seeds produced byeach of the cloned plants. The student finds that the variance in seednumber among these cloned plants is 5. From the phenotypic variancesof the genetically variable and the genetically identical plants, shecalculates the broad-sense heritability.If 80% of a population has a heterozygous phenotype, and 16% of that population shows arecessive phenotype, is that population in Hardy-Weinberg equilibrium? In other words, doesthe population obey the rules of H-W? Perform a statistical analysis to determine your finalanswer.
