According to the pedigree‚ is cystic fibrosis inherited as a dominant or as a recessive trait? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. Cystic Fibrosis is a recessive trait. You have to inherit two copies of the allele to have cystic fibrosis. If you have just

Question number 1 The disease cystic fibrosis causes the buildup of salts to occur outside the cells of the tissue that lines human lungs. The salt draws in water‚ creating sticky‚ thick mucus that causes chronic breathing difficulties and eventually death. Which cell organelle is most likely defective in this case‚ and why? Solution According the medical experiment‚ cystic fibrosis disrupts the normal functioning of epithelial cells whose working is to make sweet glands in various parts of body

that encodes for a chloride channel called the cystic fibrosis transmembrane conductance regulator (CFTR). In ductal epithelial cells‚ CFTR is highly expressed and functions to transport fluid and anions into the lumen. Dysfunction of the CFTR gene leads to a decrease in luminal fluid volume and decreased pH‚ resulting in protein precipitation within the ductal lumen and loss of normal acinar cell function. Estimated gene frequency of cystic fibrosis varies in different ethnic groups with highest

History of Cystic Fibrosis “Woe to that child which when kissed on the forehead tastes salty. He is bewitched and soon must die.” This proverb‚ dating back to European folklore in the 1700’s‚ was the diagnosis for the disease recognized today as Cystic Fibrosis (CF). In that time period the disease was usually fatal and common among infants. The excessive salt in the sweat‚ just one symptom of CF‚ made the disease identifiable. However‚ since the time of European folklore‚ various renowned scientists

Cystic fibrosis is an inherited disease of secretory glands‚ including the glands that make mucus and sweat. "Inherited" means that the disease is passed through the genes from parents to children1‚ 2. People who have cystic fibrosis inherit two faulty cystic fibrosis genes one from each parent. The parents likely don’t have the disease themselves. Cystic fibrosis mostly affects the lungs‚ pancreas‚ liver‚ intestines‚ sinuses‚ and sex organs. Mucus is a substance made by the lining of some body tissues

in her family history is a great-aunt who died of respiratory disease at 20 years old. Test results have shown high levels of sodium and chloride in her sweat. Patient A has Cystic Fibrosis‚ which is shown by her respiratory and digestive system symptoms. Cystic Fibrosis is a genetic mutation that mutates the cystic fibrosis transmembrane conductance regulator protein(CFTR). When CFTR is working properly‚ it allows chloride to leave the cell and create a balance between the amount of chloride and

According to the pedigree‚ is cystic fibrosis inherited as a dominant or as a recessive trait? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. The pedigree shows that cystic fibrosis is a recessive trait. This is shown by having one cystic fibrosis gene and having one non-cystic fibrosis gene. Now this can mean that
