Albinism is an autosomal recessive trait. Assume that there are 300 albinos (aa) in a population of 1,000,000. Based on this information, give the allele frequencies for both the recessive gene (a) and the dominant gene (A). Use this information to determine how many individuals (out of 1,000,000) would be expected to be non-carriers and how many would be expected to be unaffected carriers of the albinism trait under Hardy-Weinberg equilibrium conditions.

- 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?If a trait determined by autosomal recessive allele occurs at a frequency of 0.25 in a population, what are the allelic frequencies? Assume Hardy-Weinberg equilibrium and use A and a to symbolize the dominant and recessive alleles, respectively. Show calculation.In the genetics unit you learned that sickle cell anemia is an autosomal recessive condition. In 2016, assume in the City of Markham there are 1000 people out of 300000 people who have sickle cell anemia. Assume global warming continues for the next 50 years and in the year 2066 there are 20000 people out of 500000 in Markham who have sickle cell anemia. a)What are the allele frequencies in 2016? What are the allele frequencies in 2066? Is microevolution evident? b)Due to global warming, assume the numbers of malaria carrying mosquitoes in Markham dramatically increased between 2016 and 2066. What do you believe is the main cause of the microevolution in Markham? (Hint- refer to the 5 factors affecting microevolution and refer back…
- If the frequency of those exhibiting a monogenic autosomal recessive phenotype caused by a rare clinically relevant allele is 1/8500 in a given population, what is the carrier frequency? Please give your answer as a percentage to 3 decimal places, do not include the % symbol. ANSWER: In a population where the frequency of those exhibiting a monogenic autosomal recessive phenotype caused by only one known mutation is 1/8500 the carrier frequency is a percent.Cystic fibrosis is an autosomal recessive disease. In a population of one hundred individuals, twenty-five are found to have the disease. Assuming Hardy-Weinberg equilibrium, what is the percent of the population that are carriers for cystic fibrosisIf the Hardy-Weinberg equation enables us to use information on genotype and allele frequencies to predict the genotype frequencies of the next generation. In a population of 100,000 people carrying the recessive allele a for albinism, there are: 100 aa albinos and 1800 Aa heterozygous carriers. What is a frequency of heterozygous carriers in the next generation? Calculate the frequency for the A allele and a allele. How this will chance the frequency of alleles in a population for the following generation?
- Recall that the alleles for blood groups are A, B, O, and that A and B are each dominant to O, and A and B are codominant (AA and AO= A blood type; BB and BO = B blood type; AB = AB blood type; OO = O blood type). According to the Red Cross, in the US Asian population the alleles frequencies of A, B, an O are 18.8%, 17.6%, and 63.6%, respectively. If a mother and son from this population have blood type AB and the father has blood type B, what is the probability that the father’s genotype is BB?If the frequency of those exhibiting a monogenic autosomal recessive phenotype caused by only one known clinically relevant allele is 1/8500 in a given population, what is the frequency of the wild type allele? Please give your answer as a percentage to 3 decimal places, do not include the % symbol.If 83% of the Elmo Muppet population has a condition that makes them refer to themselves in the third person, and you know that this condition is the result of the homozygous recessive genotype (ee)… Assuming Hardy-Weinberg equilibrium, what is the allelic frequency of the dominant allele (E)? ______ Assuming Hardy-Weinberg equilibrium, what percent of the phenotypically normal population of are carriers of the recessive allele? ________ (NOTE this is asking for # that carry the allele/total "normal" population) In your answer, clearly answer with a number for both 1) and 2). Show calculations.
- Alkaptonuria is a recessive autosomal genetic disorder associated with darkening of the urine. In the United States, approximately 1 out of every 250,000people has alkaptonuria.a. Assuming Hardy-Weinberg equilibrium, estimatethe frequency of the allele responsible for this trait.b. What proportion of people in the U.S. populationare carriers for this trait? In this population, whatis the ratio of carriers to individuals affected byalkaptonuria?c. If a woman without alkaptonuria had a child withthis trait with one husband then remarried, what isthe chance that a child produced by her secondmarriage would have alkaptonuria?d. Alkaptonuria is a relatively benign condition, sothere is little selective advantage to individualswith any genotype; as a result, your assumptionof Hardy-Weinberg equilibrium in part (a) is reasonable. Could you also use the assumption ofHardy-Weinberg equilibrium to estimate the allelefrequencies and carrier frequencies of more severerecessive autosomal conditions…a) The allele frequency of albinism is 0.12 in a population of 450 individuals. If the number of individuals that are carriers of albinism is 101. Calculate the number of individuals with normal pigmentation? b) A rare disease which is due to a recessive allele (A) that is lethal when homozygous occurs within a specific population at a frequency of three in a million. How many individuals in a town with a population of 3000 will be expected to carry this allele?. In pea plants, height is controlled by a Dominant Allele (T) for Tall Height and by a Recessive Allele (t) for Short Height. If 96% of a population of pea plants have the tall phenotype, calculate the frequencies of dominant allele (T) & recessive (t) alleles. Out of the 96%, what is the estimation of how many are homozygous dominant vs. heterozygous? What is the frequency of the recessive phenotype?
