A variety of studies suggest that 10% of the world population is left-handed. It is also claimed that artists are more likely to be left-handed. In order to test this claim we take a random sample of 40 art students at a college and find that 6 of them (15%) are left handed. Which of the following is the correct set-up for calculating the p-value for this test? Roll a 10-sided die 40 times and record the proportion of times you get a 1. Repeat this many times, and calculate the proportion of simulations where the sample proportion is 15% or more. In a bag place 40 chips, 6 red and 34 blue. Randomly sample 40 chips, with replacement, and record the proportion of red chips in the sample. Repeat this many times, and calculate the proportion of samples where at least 10% of the chips are red. Randomly sample 40 non-art students, and record the number of left-handed students in the sample. Repeat this many times and calculate the proportion of samples where at least 15% of the students are left- handed. Roll a 10-sided die 40 times and record the proportion of times you get a 1. Repeat this many times, and calculate the proportion of simulations where the sample proportion is 10% or more.

5.) A man and a woman living in a tropical area where malaria is prevalent and health care is not accessible have seven children during their lifetime. The genotypes of their children are: ss, Ss, SS, ss, Ss, Ss, and SS. What must the genotypes of both parents be? Your answer should include a Punnett square to illustrate your work, and list all the genotypes and phenotypes.
3. A couple just had a baby, who has type-O blood. Upon learning the baby’s blood type, the father becomesinfuriated and accuses the mother of cheating on him. The mother has type-A blood and the father has type-Bblood. Knowing that the allele for type-O is recessive, answer the following questions.a. What is the relationship between the IA, IB, and i alleles?b. Is the father right? Or is he falsely accusing the mother? Explain. Include the genotypes of the parentsand the genotypes of their potential children.
1. The first genetic test used a short DNA sequence that was closely linked to the Huntington’s locus. People taking the test were classified as to whether they had the DNA sequence that was linked to the Huntington’s disease. This method was 95% accurate. This means that 95% of the people who had the Huntington’s-linked DNA sequence actually inherited the Huntington allele. It also meant that 95% of the people who did not have the DNA sequence linked to the Huntington allele did not inherited the wild-type allele (not the Huntington allele).Why might this preliminary test not be as accurate as a gene test for the actual Huntington’s allele? Explain.
1.)The frequency of the R allele for round seeds in a certain population of 500 peas wasfound to be 0.45. How many of them were wrinkled? How many of them had the rr genotype? How many of them were round? 2.)In humans, a dominant allele controls the formation of a cleft chin, a Y-shaped fissurein the chin caused by an atypical bone formation in the mandible (this phenotypeis also known as a chin dimple). A survey of 1200 college students found that108 of them did not have a cleft chin. What was the frequency of heterozygotes inthat student population?
3) The ability to curl ones’ tongue up on the sides (T) is dominant to not being able to roll your tongue (t). a. A woman who can roll her tongue marries a man who cannot. The first child has the same phenotype as the father, what are the genotypes of the mother, father, and this child? b. What is the probability that the second child won’t be able to roll it’s tongue?

2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
1. The frequency of a recessive disease is 9%. What is the frequency of the allele that causes s the disease? a) What is the frequency of the dominant allele? b) What is the frequency of the carriers (heterozygotes) of the disease?
3. Researchers are investigating a newly discovered condition that greatly increases the likelihood of lung damage associated with the use of e-cigarettes. They found that 2% of their study population has the condition. The researchers believe they have found a useful marker locus for assessing the presence of the condition in individuals with unknown family history. They have found that, of those individuals with the condition, 99% have the marker allele M1. Of those without the condition, 99.8% have an alternative allele M2 at the marker locus. What is the probability that an individual has the condition if they have marker allele M1 and what do you conclude about the utility of the marker locus for indirect diagnosis?
