- A sample of 1,000 Bacoleños showed the following distribution of blood groups: A=450; B= 130; AB=60; O=360. What are the allelic frequencies if the population from which they are taken are in HWE proportions? The choices are written in the order of the following alleles: IA, IB, and i, e.g., 0.5, 0.3. 0.2 Group of answer choices 0.3, 0.5, 0.2 0.28, 0.15, 0.57 0.3, 0.1, 0.6 0.4, 0.3, 0.3APOE Allelic frequency Control EOAD LOAD Vascular disease e4 0.07 0.28 0.35 0.12 e3 0.88 0.70 0.63 0.87 What group is used as a control here? Based on this data, do you think APOE e4 allele increases one’s chance to develop EOAD or LOAD? Defend your answer. Your answer has to refer to the specific data in the table. Suppose that you want to improve this case control study by controlling one more variable that is a known risk factor for Alzheimer’s disease, how will you design your groups? Specify the risk factor you want to control and how you plan to control it.Note there are no cells on this panel that have a double dose (homozygous) of the K antigen. Which of the following statements is true regarding the K+k- phenotype? Question 6 options: A) The phenotype is rare due to the high prevalence of the k antigen in the population. B) The phenotype is uncommon but does occur in about 10% of the population. C) The phenotype occurs in about 50% of the population. D) Although the phenotype is not represented on this antibody panel, it is fairly common in the population.
- A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles? What are the expected numbers of the three genotypes, assuming random matings.This is the information collected by mission doctors in a remote isolated tribal village. Local people displayed the following, in the following numbers: 104 were not resistant to malaria and did not have the sickle cell anemia; 18 had the sickle cell anemia; 33 were resistant to malaria and did not have the sickle cell anemia. Determine the allele frequencies in this population. I am only asking for allele frequencies. Show your calculations Thank youA study on blood types in a population found the following genotypic distribution among the people sampled: 1101 were MM, 1496 were MN and 503 were NN. i) calculate the allelic genotypic frequencies. ii) using x² test, determine whether or not this population is in Hardy-Weinberg equilibrium. Important information from the x² distribution is given in the picture attached.

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?I asked this question before but the solution was not correct and I'm really trying to figure out how to do this to get the correct answer. Please show work!DNA typing is used to compare evidence DNA (E) left at a crime scene to two suspects(S1 and S2). Suspect 1 is excluded by the evidence, but suspect 2 remains included.

- The following frequencies were gathered in an African population affected with sickle-cell anemia: SS, 75.5%; Ss, 23.0%; ss, 1.5% (S = normal hemoglobin allele; s = mutant hemoglobin allele). Calculate the genotypic frequencies and determine whether this data represent a population that is in HWE.Tay-Sachs disease is a recessive genetic disease. Individuals with this disease rarely survive past the age of four. In the general population, approximately 1 person in 300 carries the allele for this disease. However, in some populations, including the Irish Americans, the Ashkenazi Jews, and the Cajuns from Louisiana, the proportion of Tay-Sachs carriers is much higher (1 in 27 to 1 in 50) than in other populations. Such high frequency of an otherwise rare allele is expected when Question 24 options: populations experienced disruptive selection populations were founded by a small number of settlers the allele is advantageous at the heterozygous state populations have higher than average mutation rates populations experienced stabilizing selectionYou are examining a scorpion population within the Las Vegas area. Your field team is able to capture 200 yellow scorpions and 450 brown scorpions. You know that the color brown (B) is dominant over the color yellow (b). Based on this information, please answer the following questions. Be sure to show your work. What is the allele frequency of each allele? What percentage of scorpions in the population are heterozygous?
