.. Nowadays, newborn babies are required to be tested for
phynylketonuria (PKU), an autosomal recessive genetic disorder. If
untreated, individual homozygous for PKU suffer mental retardation. In a
recent year, 4 PKU babies were detected out of 126,000 tested. Assuming
Hardy-Weinberg conditions, what is the frequency of the PKU gene in this
population (Give your answer in decimal number with 3 decimal places)?

- Nieman-Pick Syndrome involves a defective enzyme, sphyngomylinase. It is usually fatal before the age of 3. The defective allele frequency is 0.01 in Ashkenazi populations. Let’s call the healthy allele A, and the lethal allele a. a) What is the frequency of allele A?

You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive. A deadly virus infects all of the RR mountain goats in the population (above), killing all individuals of this genotype and leaving the population with only the rr and Rr mountain goats. a) Calculate the new allele frequencies for this population.

- Sickle cell anemia is homozygous recessive (aa).arrow_forwardA certain population of Sistrurus milarius, there exists an allele “d" which has the frequency of 25%. This allele confers the ability to allow the organism to grow to lengths exceeding 3m. This population occurs in the northern 2/3 of Alabama. Out of a population of 80, find the following: # of individuals who are homozygous dominant # individuals who have the recessive diseasearrow_forwardThe prevalence (frequency) of sickle-cell disease in Canada is quite low, affecting 1/3800 individuals. However, in some African populations 1/25 individuals are affected by sickle-cell disease. The difference in frequency of this allele within the differing populations has to do with the adaptation pressures that exist in the different environments. Individuals with the heterozygous genotype have a survival advantage in environments where the disease malaria is prevalent as the presence of this mutant allele leads to resistance to malaria. Therefore, the sickle-cell disease tends to be more frequent in environments where the malaria parasite is most common. Question: Explain why the sickle-cell disease remains frequent in some populations while it exists in very low frequency in other populations.arrow_forward
- Consider the case of a hypothetical genetic disease called WhySciEleven (WSE), an inherited disease that results to the inability to complete production of an amino acid “moduleactivity” that results in brain damage if untreated.

- The eugenic movement was created in the early 20th century by Sir Francis Galton. Its aim was to improve the genetic pool of the human population by selective breeding. One idea was to discourage individuals with Mendelian autosomal recessive diseases to have children. However, the fallacy of this idea is shown by the fact that recessive lethal alleles (that are never found in homozygosity) can persist in populations for hundreds to thousands of generations. Which one of the following statements best explains the persistence of those alleles in populations? There is heterozygote advantage in those populations. Recessive alleles keep being produced by mutation. Recessive alleles cannot be selected against when present in heterozygotes. Genetic drift keeps recessive alleles at a relative high frequency in populations. Consider the action of mutation and of genetic drift in a population. What do you expect genetic variation will be in a…arrow_forwardPolydactyly – extra fingers or toes–is one symptom of Ellis-van Creveld syndrome. The syndrome is commonly found among the Old Order Amish of Pennsylvania, a population that experiences the “founder effect”. This disease is more concentrated among the Amish because they marry within their own community, which prevents new genetic variation from entering the population. Children are more likely to inherit two copies of the recessive genes leading to the genetic disease. 1. Is this an example of genetic drift? Explain your answer. 2. Would the frequency of the disease be different in a larger population? Explain your answer.arrow_forwardPlease asaparrow_forward
