Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
Using the HardyWeinberg Law in Human Genetics Suppose you are monitoring the allelic and genotypic frequencies of the MN blood group locus (see Question 2 for a description of the MN blood group) in a small human population. You find that for 1-year-old children, the genotypic frequencies are MM = 0.25, MN = 0.5, and NN = 0.25, whereas the genotypic frequencies for adults are MM = 0.3, MN = 0.4, and NN = 0.3. a. Compute the M and N allele frequencies for 1-year-olds and adults. b. Are the allele frequencies in equilibrium in this population? c. Are the genotypic frequencies in equilibrium?
House mouse (Mus musculus) Gene of interest: B4galnt2 (encodes glycosyltransferase enzyme) • Allele R: Associated with prolonged bleeding due to issues with blood clotting; associated with resistance to bacterial infections due to absence of intestinal expression. Allele C: Associated with increased susceptibility to bacterial infections; not associated with prolonged bleeding. A B C The population is closed; there are no new mice coming in. The cages are setup to allow for random mating. The B4galnt2 gene is not associated with any mating preferences or non-random mating patterns. Studies have shown that mutations in this locus are extremely rare. The population is EXTREMELY large. The population is kept in well maintained environment, free of bacterial infections. The mouse food is supplemented with a low dose of blood coagulator, which helps the blood clot and eliminates any prolonged bleeding. None of the genotypes display any side effects to this medication. The population is…
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?

Hardy-Weinberg Problems Please be sure to SHOW ALL WORK in order to get credit. This assignment will be graded for accuracy. *Hint: Remember what p and q represent. Determine first if I am asking for allele frequency or genotype/phenotype frequency. Then determine which equation is appropriate. What does p and q represent in the equations? Which equation do you use if I am asking for allele frequency? If the frequency of the recessive allele is 0.1, what is the frequency of the dominant allele? If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele? If the frequency of the dominant allele is 0.6, what is the frequency of the homozygous dominant genotype? If the frequency of the homozygous recessive genotype is 0.81, what is the frequency of the recessive allele? If the frequency of the homozygous dominant genotype is 0.25, what is the frequency of the dominant allele? If the frequency of the…
Consider a population of 200 individuals. For a trait expressing simple dominance, genotype frequencies are WW = 0.1, Ww= 0.7, ww = 0.2. What are the allele frequencies of the W and w alleles in this population (where p is the frequency of the dominant allele). p = 110, q = 90 p = 20, q = 80 p = 0.45, q = 0.55 p = 0.55, q = 0.45 p = 0.2, q = 0.8 p = 90, q = 110
There are two existing hypotheses for an unusually high frequency of a deleterious recessive allele in a certain population other than it is hidden in the heterozygous genotype and not exposed to selection. Explain what these two likely hypotheses are and how you could distinguish between them based on your understanding of the applicable assumptions that are part of the Hardy-Weinberg Equilibrium Model
For these experiments assume allele A = red, allele a = white . There are three flower colors (phenotypes and genotypes) for this species where AA=red, Aa = pink, aa = white. • A population of Four O-Clocks is in Hardy-Weinberg equilibrium and no evolutionary forces are acting on the population. Bees are introduced into the population. Individual bees only visit a single color of flower so that red flowers only mate with red flowers, pink with pink, and white with white. What will happen to the genotype frequencies in the next generation? O The proportion of reds and whites will increase over pinks. O The population will remain in Hardy-Weinberg equilibrium. O The proportion of pinks will increase over reds and whites. The proportion of reds will increase over pinks and whites.
