Answer:
1. 1/2 * 1/2 = 1/4
Explanation:
Based on the information, it is clear that both man and woman are heterozygous for the Cystic fibrosis.
C= No CF or normal (dominant)
c = CF (recessive)
Cc (woman) x Cc (man)
Cc genotype produces two types of gametes, C & c in equal proportions, 1/2 or 50%.
| C (1/2) | c (1/2) | |
| C (1/2) | CC (1/2 * 1/2 = 1/4)-Normal | Cc (1/2 * 1/2 = 1/4)-Normal |
| c (1/2) | Cc (1/2 * 1/2 = 1/4)-Normal | cc (1/2 * 1/2 = 1/4)- CF |

Mike and Mary are planning a family. In addition to their love for each other and for Game of Thrones, they have something else in common. They each have a history of cystic fibrosis in their family. Cystic fibrosis (CF) is an autosomal recessive disease. i. Mary does not have CF, two of her three sisters have CF, and her mother didn’t have it. But her father did. ii.

QUESTION 45 Nicole is a carrier for thalassemia, an autosomal recessive blood disorder, but her husband is not. Her husband is a carrier for cystic fibrosis, also an autosomal recessive disorder, but Nicole is not. What is the chance that their daughter is a carrier for BOTH thalassemia and CF?

1) You have been hired as a genetic counselor. Your first patient is a young woman named Lei who comes to you because her brother has cystic fibrosis. (Learn more about this disease in the PowerPoint slides – find out how it is inherited, is it dominant or recessive?) Lei is healthy but would like to know the risk that she is a carrier for the disease. Both her parents are healthy as is her older sister. a. Fill in...

You must try to answer both questions: Cystic fibrosis (CF) is an inherited disorder that causes severe damage to the lungs, the digestive system and other organs within the body. CF affects cells that produce thin and slippery mucus and cause the secretions to become sticky and thick. CF is caused by a deletion mutation on chromosome 7. In order for a child to have cystic fibrosis they must inherit a defective gene from each of his/her parents a) Rob...

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...
