The Turner Kieser Syndrome (or nail patella syndrome) is a dominant human disease (prevalence about 1/100.000), which impairs the normal development of, nails and kneecaps (patella). In the following study the mutant allele for this gene is noted "M" and the wild type allele "m". On the family tree below black symbols (circles for women and squares for men) indicate people suffering from KSS and open symbols represent healthy persons.

In a study conducted by an undergraduate student, Simran obtained data showing that approximately 75% of the European Northern human population demonstrate the expression of a phenotype directly associated with the homozygous dominant genotype, while 25% display the mutant phenotype despite their genotypes being homozygous dominant. Propose two hypotheses for this observation.
What is the equilibrium heterozygosity for a SNP in apopulation of 50,000 when the mutation rate is 3 × 10−8 ?

I have seen that this was answered as C, Why is the answer C, how is that not evidence of it being genetic? Shouldnt it be none of the above? Question: Of the following, which supports the idea that alcoholism has no genetic or a low genetic component? a) Some strains of mice select alcohol over water 75% of the time, whereas others shun alcohol. b) The concordance value is 55% for MZ twins and 28% for DZ twins. c) Biological sons of alcoholic men who have been adopted have a rate of alcoholism more like that of their adoptive fathers. d) There is a 20% to 25% risk of alcoholism in the sons of alcoholic men. e) None of these.

Sickle cell anemia is a genetic disease most common in those of African ancestry that results from the mutation of a single basepair. This mutation results in a change to the hemoglobin protein. In this experiment, “S” will represent the normal allele and “s” thesickle allele. They are codominant alleles. Therefore, SS is normal, Ss is not fatal but mildly symptomatic, and ss is debilitating,painful, and often fatal. After hundreds or even thousands of generations, both alleles are still common in those of African ancestry. How would you explain this?
in a randomly mating laboratory population of Drosophila, 4% of the flies have black bodies, and 96% have brown bodies. Flies with brown bodies always have at least one parent with a brown body. What is the frequency of heterozygotes in this population? 0.04 0.16 0.08 0.32 The period gene of Drosophila melanogaster encodes for a stretch of Thr-Gly repeated in tandem. In natural populations, the three most common alleles encode for 17, 20 and 23 Thr-Gly repeats. The amplification by PCR of the allele encoding for 20 Thr-Gly repeats produces a fragment of 320 bp. Using the same set of primers, what is the size expected when amplifying the 17 Thr-Gly allele? 317 303 314 302 in a certain species of plant loci A, B and C have an additive effect on the colour of the flower. Alleles A, B, and C are dominant and alleles a, b and c are recessive. Knowing that a plant with genotype AAbbCc has a…
You are interested if whether several genes of a certain species of beetle assort independently. So, you conduct several generations of matings, and after you have collected all your data, you are ready to analyze your results. You conduct a Chi2 test to test your hypothesis. You have 6 groups and calculate a Chi? = 13.22. Given that the critical value at 0.05 level of %3D significance = 11.07 at df = 5, %3D (A) State your null hypothesis. (B) Should you accept or reject your null hypothesis? (C) Why did you arrive your decision in (B)?
