(3 parts for the answers) Cystic Fibrosis Cystic fibrosis is an autosomal recessive disorder that affects 1 in 3 000 newborns with a Caucasian background. It causes thick mucus build up in various organs and can cause damages and problems in respiratory and digestive systems. --What is the frequency of the cystic fibrosis allele in the Caucasian population? Show all your work and express your answer as a value between 0 and 1 rounded to two decimal places --What percentage...

Sheree is referred to a genetic counselor because a cystic fibrosis (CF) test done as a routine part of her prenatal care indicated that she is a carrier of the most common mutant allele. Sheree is stunned, because no one in her family has the disease. She is 26 years old. The genetic counselor would most likely Multiple Choice o explain autosomal recessive inheritance and suggest that Sheree's husband be tested for CF. O explain autosomal dominant Inheritance and suggest...

Cystic fibrosis (CF) is caused by recessive loss-of-function mutations for a cell surface protein expressed in the mucus membranes of intestines and lungs. Until recently, few affected individuals survived to reproductive age. In Caucasian populations, CF affects 1 infant in 2,500 births. What is the frequency of CF homozygotes? Based on the genotype frequency, what is the frequency of the CF allele? Given a selection coefficient of 1, what would be the mutation rate needed to keep CF in the...

3. Cystic fibrosis (CF) is an autosomal recessive disorder (cc) and is one of the most common life-shortening genetic diseases. In the United States, 1 in 4,000 children are born with CF. Symptoms of cystic fibrous include the production of salty sweat and thickened mucus in the lining of the lungs and air passages. The thickened mucus obstructs airways and promotes the growth of disease-causing bacteria in the lungs. Most individuals with cystic fibrous die in their 20s and 30s...

Use the following information to answer the next question. In populations where it is common for first cousins to marry, some autosomal recessive disorder such as albinism and phenylketonuria are far more likely to occur than elsewhere. 46) If the frequency of a recessive allele changes from 0.0001 to 0.01 after several generations, the most probable reason is that A. random mating is occurring B. non-random mating is occurring C. a high rate of mutation is involved D. inbreeding causes...
