What is the probability of a child having cystic fibrosis if one of her parents was homozygous dominant and the other was a carrier for cystic fibrosis?

Assuming that each parent is a carrier for cystic fibrosis (has the genotype Ff), the probability that their second child will develop cystic fibrosis is one fourth. The probability doesn't change with the number of children they have. For each pregnancy, the chance that the child will have cystic fibrosis (have the genotype ff) is exactly the same.


What is the sequence of amino acid in cystic fibrosis?

The sequence of amino acids in cystic fibrosis is caused by a mutation in the CFTR gene, which leads to the production of a faulty cystic fibrosis transmembrane conductance regulator protein. This mutated protein results in abnormal function, leading to the characteristic symptoms of cystic fibrosis such as thick mucus production.


Name two genetic disorders?

Two genetic disorders are Turner's syndrome and cystic fibrosis.


Is cystic fibrosis more common in boys or girls?

i copied the following answer from health.howstuffworks.com Unlike some other genetic conditions, cystic fibrosisoccurs equally as often in men and women. The genetic mutation for cystic fibrosis occurs on chromosome 7 and is not impacted by gender. The severity of symptoms related to cystic fibrosis, however, does vary in men and women. In particular, girls with cystic fibrosis have more difficulty with meeting growth milestones and experience more lung-related problems compared to boys. Due to these more severe symptoms, women with cystic fibrosis have shorter life expectancies than men. It is estimated that men with cystic fibrosis live four to five years longer than women with cystic fibrosis, Moreover, under the age of 20, girls have a 60 percent greater chance of dying due to cystic fibrosis complications compared to males [source: Cystic Fibrosis Worldwide]. As a result, the prevalence of male adults with cystic fibrosis is greater than the prevalence of female adults with cystic fibrosis, suggesting a male advantage with the disorder. Cystic fibrosis researchers argue that this gender difference is the result of early-onset lung infections in girls. Girls appear to develop these infections earlier in life than boys, leading to more severe cystic fibrosis complications, and even death. Girls also appear to have greater difficulty maintaining a healthy body weight after puberty compared to males, which places girls at greater risk for cystic fibrosis complications. It appears that this gender gap can narrow if girls are provided with more intensive medical care. In fact, girls and women who receive regular intravenous antibiotics, regardless of their condition, have improved survival rates [source: Cystic Fibrosis Worldwide]. As a result, countries with excellent health care, such as Scandinavian countries, do not have a difference in the survival rate of men and women with cystic fibrosis. i hope it helps:)


Do cystic fibrosis patent have trouble breathing around perfume?

Yes, individuals with cystic fibrosis can have increased sensitivity to strong odors like perfume, which can trigger respiratory symptoms such as coughing, wheezing, and shortness of breath. Perfume particles can irritate the airways and exacerbate existing breathing difficulties in people with cystic fibrosis. It is advisable for individuals with cystic fibrosis to avoid exposure to strong odors or use fragrance-free products to prevent respiratory distress.
