Cystic fibrosis is an autosomal recessive disease characterized by two copies of a mutated CFTR gene. If one in 100 (hypothetical scenario, not reality) people in the United States have cystic fibrosis, calculate the p and q frequency for the normal allele (p) and the mutated allele (q). Based on those calculations, what percentage of individuals would be expected to be homozygous dominant?

- Suppose there is an autosomal locus of 2 alleles, A1 and A2, with probabilities (frequencies) p1 and p2, and the genotype probabilities (frequencies) are P(A1A1) = p1*p1, P(A1A2) = 2*p1*p2, and P(A2A2) = p2*p2, respectively. Prove the Hardy-Weinberg Law, i.e., after one generation of random mating, the genotype probabilities (frequencies) in the offspring are also P(A1A1) = p1*p1, P(A1A2) = 2*p1*p2, and P(A2A2) = p2*p2. Hint: List all possible combinations of random mating. Then list the probabilities of the resulting genotype probabilities (frequencies) in the offspring. Combine the probabilities of random mating and resulting genotype probabilities (frequencies) in the offspring.arrow_forwardTwo parents, both with blood type A, have three children in a row with blood type O. a. Is this possible? If not, why not? If so, give the genotypes of the parents. i. What are the odds that, given the genotypes you list in 2.e., that the described scenario would actually happen? b. Could other children of this pair be born with blood type AB? Why not?arrow_forwardWhat is the first variable that can be calculated given these data, and what is the final variable we are requesting you to calculate?

- Consider a locus with two alleles, A and a. If the frequency of AA is 0.30, what is the frequency of A under Hardy-Weinberg?arrow_forwardAchondroplasia is a hereditary condition caused by a dominant allele in humans (dominant allele A). This disorder affects bone growth specifically in long bones of the upper and lower limbs by preventing the ossification of bones from cartilage. Determine the genotypes of the parents and offspring for the following family scenarios in a and b below. One parent with the Achondroplasia phenotype and a normal parent have 2 children. Both children have the Achondroplasia phenotype NOTE: You must draw a Punnet square to determine the possible genotypes of te children. When two alternative genotypes are possible for an individual, indicate both.arrow_forwardCan you explain the answer and how to find it ?arrow_forward
- Tay-Sachs disease in humans is caused by a recessive allele. The disease is characterized by mental deficiency and blindness, with death occurring by 4 years of age. Among Ashkenazi Jews of central European ancestry, about 1 in 3600 children is born with the disease. Assume Hardy-Weinberg equilibrium and calculate the frequency of the Tay- Sachs allele in this population. Round your answer to the nearest 0.001.

It applies to Mendelian traits that are controlled by one pairof alleles.c. 2pq = heterozygous individualsd.
