Cystic fibrosis is an autosomal recessive disorder that runs in ann's family. she has created a pedigree of the known occurrences of cystic fibrosis in her family. which individuals are symptomless carriers? choose all correct answers.

Cystic fibrosis  is caused by changes in genes that function to regulate the distribution of salt in the human body. Changes or genetic mutations will make the levels of salt in sweat increase. This condition affects the mucus in the respiratory tract, digestion, and the reproductive system becomes thick and sticky.

Further explanation

Cystic fibrosis is a hereditary disease that causes mucus in the body to become thick and sticky. Cystic fibrosis is not a contagious disease, but rather the sufferer is more susceptible to contracting the infection if it is near or in contact with people with infectious diseases.

Under normal circumstances, mucus which acts as a lubricant in the body is liquid and slippery. In patients with cystic fibrosis, there are abnormalities in genes that regulate the flow of fluid and salt in cells.

This gene abnormality causes mucus to become sticky and inhibits a number of channels in the body. The respiratory tract is one of them.

Gene mutations in patients with cystic fibrosis are inherited from both parents. If a child receives this gene mutation only from one of his parents, then he only becomes a carrier for cystic fibrosis. A carrier does not suffer from cystic fibrosis, but can reduce this disorder to the offspring.
