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?

In a population of 500 individuals in Near East, the frequencies of the dominant and recessive alleles for autosomal recessive genetic disease PKU are 0,89 and 0,11 respectively. A is used to indicate the dominant allele, a is used to indicate the recessive allele. Assuming random mating, what are the expected genotype frequencies?
The frequency of the A1 allele is p = 0.4, and that of the A2 allele is q = 0.6. The observed genotype frequencies are as follows: f(A1A1) = 0.25 f(A1A2) = 0.36 f(A2A2) = 0.39 Is there a Hardy-Weinberg equilibrium in the population?
