Please use them for each.Solve questions 1-10 using dosage and calculations.Give typing answer with explanation and conclusion 6. In a prospective cohort study, it is found that men who drink alcoholic beverages are more likely to develop lung cancer than men who are not drinkers. However, among smokers the risk for lung cancer among drinkers and nondrinkers is the same. Also, among nonsmokers the risk for lung cancer among drinkers and nondrinkers is the same.

- Can you please do Q1,Q2 AND Q3? Please ?Q6. Many different mutations (>1500 to date) in the CFTR gene can cause Cystic Fibrosis (CF). The disease shows allelic heterogeneity and many CF sufferers are compound heterozygotes i.e. they have two different mutations, one in each of their copies of the CFTR gene. ~1 in 25 people in Australia are carriers for CF (an autosomal recessive disease). DNA tests are used to detect CF mutations in carriers but it is too expensive to test, or screen for all mutations so only the most common mutations are tested for. A typical CF carrier screen is 90% accurate, i.e. 10% of mutations are missed by the screen. a. Use Bayesian Analysis to calculate the probability that a woman who: a) has no family history of CF; and b) tests negative (negative means no mutation is found) on a mutation screen, is a carrier. Provide answers to 3 decimal places. Scenario A woman is a Scenario B woman is not a carrier carrier Prior Probability Cond. Probability Joint probability Posterior probability b.

Provide the genotype and phenotype ratios using the Punnett square given below. Genotypes Phenotypes 3. When an offspring's phenotype is a combination of the parents' phenotypes it is called incomplete dominance. Both the alleles are expressed.

- Please answer fast 1. Huntington disease is a neurodegenerative disease that appears in affected people late in life. It is a dominant trait controlled by a single gene and the dominant Huntington allele is rare. Suppose that Joe is diagnosed with Huntington disease. He is surprised because both of his parents are over 70 years old but do not have the disease. He talks to his parents about this and finds out that there is no history of Huntington disease on his father’s side, but his maternal grandfather and one of his mother’s aunts, who had both died before he was born, had suffered from Huntington disease. a. Does this story represent variable expressivity, or incomplete penetrance? b. Deduce, as much as you can, the genotypes of Joe, his mother, his father, and his maternal grandfather .Please only solve the Q2 as it is a subpart of Q1can u help with q. 3? Thank you
