The incidence of Tay Sachs, an autosomal recessive genetic disorder, is approximately 1 in 3,500 in a certain population of Ashkenazi Jews. Assuming Hardy-Weinberg equilibrium, what is the frequency of carriers for the Tay Sachs allele in this population?

2) Tay-Sachs disease is an autosomal recessive neurological disorder that is fatal in infancy. Despite its invariably lethal effect, Tay-Sachs disease occurs at very high frequency in some Central and Eastern European (Ashkenazi) Jewish populations. In certain Ashkenazi populations, 1 in 1000 infants has Tay-Sachs disease. Population biologists believe the high frequency is a consequence of genetic bottlenecks caused by pogroms (genocide) that have reduced the population multiple times in the last several hundred years. a) In the population described,...
Give the Hardy–Weinberg expected genotypic frequencies for an autosomal locus with three alleles, where the frequencies of alleles A1, A2, and A3 are defined as p, q, and r, respectively. Set the problem up and show your work. Tay–Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews, the frequency of Tay–Sachs disease is 1 in 3600. If the Ashkenazi population is mating randomly for the Tay–Sachs gene, what proportion of the population consists of heterozygous carriers of the Tay–Sachs...
Tay-Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews of central European ancestry about in 1/3600 children are born with Tay-Sachs disease. What is the frequency for being a carrier for Tay-Sachs in this population? A carrier does not show the trait but can pass it on to his/her offspring.
Infantile Tay-Sachs disease is a neurological disorder that causes a progressive deterioration of nerve cells resulting in seriously impaired mental and physical abilities. It usually results in death by the age of four. Infantile Tay-Sachs is a recessive disorder (aa) affecting 1 in 3000 individuals. (show your work) (10pts) a) What is the frequency of the "aa" genotype in this population? b) What is the frequency of the "q" allele? c) What is the frequency of the "p" allele? d)...
9. Cystic fibrosis is a genetic disease caused by an autosomal recessive allele at a single locus. In a survey of 100,000 people in Pennsylvania, 7 people had the disease. Assuming the population is in Hardy-Weinberg equilibrium, find: a. P: é o ö 10. How many people of 100,000 surveyed would you expect to be carriers of the cystic fibrosis allele?
Cystic fibrosis is an autosomal recessive disorder. In one population, the frequency of affected individuals (A 2 A 2) is 0.0004 Assuming that this population is under Hardy- Weinberg equilibrium, calculate all allele frequencies and genotype frequencies. Enter your numerical answers in the boxes below. Express each answer to four decimal places. Frequency of A1: Frequency of A2: Frequency of homozygous dominant: Frequency of homozygous recessive: Frequency of heterozygous
9 % of a small sect are born with the lethal autosomal recessive trait of Tay-Sachs - 1. What is the frequency of the recessive gene in this population? -2. What is the frequency of the dominant gene? -3. What is the frequency of the heterozyous in this population? -4-5. What is the probability that the first born child of a healthy couple who are members of the sect, will have Tay-Sachs?
Two people who are “carriers” of (heterozygous) for Tay Sachs disease marry and plan a family. What is the probability that a child from this union will suffer from Tay Sachs disease. (Recall that this is an autosomal recessive disorder, that is, homozygous recessives have the disease.) a. Zero b. 0.25 c. 0.5 d. 0.75 e. 1.0 6. At Hardy-Weinberg equilibrium, heterozygotes are the most common genotype in the population when- a. b. c. d . p> 0.67 q>0.67 and...
2. Assume a population is in Hardy-Weinberg equilibrium for a given genetic autosomal trait. What proportion of individuals in the population are heterozygous for the gene if the frequency of the recessive allele is 1%.
1. Tay-Sachs is an autosomal recessive disorder, which is the inability for infants to breakdown gangliosides in the CNS, which overtime build-up and destroy neurons. As the disease progresses, the child loses muscle control. Eventually, this leads to blindness, paralysis and death. If you have a family history of Tay-Sachs disease or if you're a member of a high-risk group and plan to have children, doctors strongly recommend genetic testing and genetic counseling. Scott and Tina are a young couple...
