QUESTION PART A: About 1% of the population has a particular genetic mutation. 900 people are randomly selected.

Find the mean for the number of people with the genetic mutation in such groups of 900.

QUESTION PART B: About 4% of the population has a particular genetic mutation. 400 people are randomly selected.

Find the standard deviation for the number of people with the genetic mutation in such groups of 400. Round your answer to three decimal places

Expert Solution

Part A)

About 1% of the population has a particular genetic mutation. This is same as the probability that a randomly selected person from this population has the genetic mutation is 0.01

Let X be the number of with the genetic mutation in such groups of 900. We can say that X has a Binomial distribution with parameters, number of trials (number of persons randomly selected) n=900 and success probability (the probability that a randomly selected person from this population has the genetic mutation) p=0.01

Using the formula for Binomial expectation, we can say that the expectation of X is

ans: the mean for the number of people with the genetic mutation in such groups of 900 is 9

Part B)

About 4% of the population has a particular genetic mutation. This is same as the probability that a randomly selected person from this population has the genetic mutation is 0.04

Let X be the number of with the genetic mutation in such groups of 400. We can say that X has a Binomial distribution with parameters, number of trials (number of persons randomly selected) n=400 and success probability (the probability that a randomly selected person from this population has the genetic mutation) p=0.04

Using the formula for Binomial standard deviation, we can say that the standard deviation of X is

ans: the standard deviation for the number of people with the genetic mutation in such groups of 400 is 3.919

A certain genetic mutation occurs in 5% of the population of Whoville. The mutation causes otherwise normal adult Whos to grow green tail feathers during full moons. A test for this mutation has a sensitivity of 95% and a specificity of 98%. This means that the probability that a Who with the mutation tests positive is 95%, and the probability that a Who without the mutation tests positive is 100%-98%=2%. If a random adult Who is tested for the mutation, then...

Segawa syndrome is a genetic mutation that affects the synthesis of dopamine in the body. People with this disorder walk clumsily and have involuntary muscle contractions. Please draw a diagram representing the pathway of neurons involved in segawa syndrome, label the following feature: CNS- central nervous system, spinal nerve, cell body, axon, dendrites, affected organ, afferent pathway, efferent pathway, interneuron, sensory neuron, motor neuron, and synapse.

A patient has a genetic mutation in the gene for glutaminase that significantly reduces the efficiency of this enzyme, leading to a decrease in glutamatergic signaling. Which of the following could potentially compensate for this? a. A downregulation of aspartate aminotransferase b. A downregulation of VGLUT c. An upregulation of neuronal glutamate transporters d. An upregulation of VIAAT

Question: You determine that a particular gene in a peson with a genetic disease is the same size as that of a healthy individual. You suspect that the arises from a point mutation (a single nucleotide change that results in a defect in the protein.) Describe a how you could confirm this hypothesis. Comment: We learned about Sanger Sequencing and Next Gen sequencing in class. Could you use either of these and if yes why would you use one over...
