Cystic Fibrosis has an autosomal recessive pattern of inheritance, therefore, neither male nor female is more likely to inherit the disease.
There are four different scenarios that can occur to "pass on" the disease.
First, both parents have CF, and in this scenario all offspring would have CF as well.
Second, One parent has CF and the other doesn't. This scenario has two subgroups. The parent that does not have CF could either be a carrier or have no CF gene. If the non-CF parent is a carrier then 3 out of 4 children would inherit CF. If the non-CF parent is not a carrier then 2 of 4 children would inherit it.
Third, both parents are carriers, and in this scenario 2 of 4 offspring would inherit CF.
Fourth, one parent is a carrier and the other is not. This would yield 1 out of 4 offspring inheriting CF.
The genes for CF are located on non-sex chromosomes (autosomes) and therefore there is no correlation to Cystic Fibrosis and sex.

Is it true that if tissue damage is very severe tissue repair is more likely to occur by fibrosis or scarring?

What are inherited traits that its offspring will most likely inherit for butterflies?

How do geneticists use mendel's results from experiments to help them understand genetics?
Geneticists used the laws of segregation and independent assortment even today, to assess the risk of genetic disease in offspring for example. Healthy couples can go for genetic testing for diseases such as thalasemia, cystic fibrosis and sickle cell anaemia and be told how likely it is their child will have the disease.
A recessive genetic disorder affecting the mucus lining of the lungs leading to breathing problems the other difficulties?
The disorder you're referring to is likely Cystic Fibrosis (CF). It is caused by mutations in the CFTR gene, which disrupts the regulation of salt and water in epithelial cells, leading to thick, sticky mucus buildup in the lungs and digestive system. This can result in severe respiratory issues, frequent lung infections, and complications in nutrient absorption. Early diagnosis and treatment can help manage symptoms and improve quality of life.
Where is most likely the site of fertilization in a female?
The most likely site of fertilization in a female is in the fallopian tubes. Once an egg is released from an ovary, it travels through the fallopian tube where it may encounter sperm and become fertilized.
What are the gender statistics for people with cystic fibrosis?
Men and women are equally likely to inherit this.
Which race is most likely to get cystic fibrosis?
Cystic Fibrosis is more prevalent among people with European and Caucasian decent. 70,000 people worldwide suffer from the condition, and an estimated 2,500 Caucasians inherit the disorder.
What resaerch is being done on cystic fibrosis?
Unfortunately, cystic fibrosis cannot be cured. There is medication getting better all the time but now, the government in the UK have not funded in any cure. This means that in the UK, we may only find a cure if a devoted medical professional actually spent his own time to find the cure
To be a cystic fibrosis carrier do your parents have to have a cystics fibrosis gene?
Yes, since the disease is a recessive inherted trait BOTH parents must carry the gene but will not have the disease itself. Approximately 30,000 people in the United States have cystic fibrosis. An additional ten million more-or about one in every 31 Americans-are carriers of the defective CF gene, but do not have the disease. The disease is most common in Caucasians, but it can affect all races.
Two parents who were phenotypically normal had to children The oldest was also phenotypically normal but the younger child had cystic fibrosis what is happening in the cross?
Cystic fibrosis is an autosomal recessive genetic disorder, meaning that a child must inherit two copies of the mutated gene (one from each parent) to express the condition. In this scenario, both parents are likely carriers of the cystic fibrosis allele (genotype Cc), where "C" is the normal allele and "c" is the mutated allele. The older child is phenotypically normal, which could mean they are either homozygous dominant (CC) or a carrier (Cc), while the younger child inherited two copies of the mutated allele (cc) from both parents, resulting in cystic fibrosis. This cross illustrates Mendelian inheritance patterns, where two carrier parents can have a child with a recessive condition.
Are women beyond a particular age more likely to give birth to a baby with cystic fibrosis?
Yes but depending on your age and the risk you are willin to take
How can you get cystic fibrosis?
For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Donate you eggs if you have cystic fibrosis gene?
The general qualifications for donating eggs are quite strict. As well as being within normal weight, height, and IQ, they often will ask for a family history of any diseases, including cystic fibrosis. They would most likely refuse an egg donation from anyone with any diseases than could be passed on to a child.
Would a person with Cystic Firosis be sterile?
Cystic Fibrosis can but not always lead to fertility problems. In most men with CF, the tubes that carry sperm are blocked, which causes infertility (approx 95%). Because underweight women are more likely to have irregular menstrual cycles, the nutritional problems associated with CF may affect fertility. hope this helps
How does cystic fibrosis affect the immune system?
Cystic fibrosis affects primarily lungs and pancreas, not immune system. But a patient affected is debilitated and it would decrease the fuction of various systems, like the immune A CF patient that has had a lung transplant would have an impaired immune system because of the medication given for rejection. The medication would suppress the immune system so that the patients' body would be more likely to accept the new organ(s), but also making the patient more susceptible to other illnesses.
Is it true that if tissue damage is very severe tissue repair is more likely to occur by fibrosis or scarring?
fibrosis
Neonatal cystic fibrosis screening?
DefinitionNeonatal cystic fibrosis screening is a blood test that looks for increased levels of immunoreactive trypsinogen (IRT), an enzyme produced by the pancreas. The test is performed on newborns to screen for cystic fibrosis (CF).Alternative NamesCystic fibrosis screening - neonatal; Immunoreactive trypsinogen; IRT testHow the test is performedA sample of blood is either taken from the bottom of the baby's foot of a vein in the arm. A tiny drop of blood is collected onto a piece of filter paper and allowed to dry. The dried blood sample is sent to a lab for analysis.How to prepare for the testThere is no special preparation needed.Some states include this test in the routine newborn screening tests that are done before the baby leaves the hospital.If you live in a state that does not perform routine CF screening, your health care provider will explain whether testing is needed.How the test will feelThe brief feeling of discomfort will probably cause your baby to cry.Why the test is performedChildren with CF who are diagnosed early in life and start treatment at a young age may have better nutrition, growth, and lung function. Newborn screening tests allow doctors to identify children with CF before they have symptoms.Normal ValuesNormal values vary from lab to lab. Ask your doctor or testing center for details.What abnormal results meanIt is important to remember that a positive screening test for cystic fibrosis does not diagnose cystic fibrosis. If your child's test is positive, further tests will be done to confirm the possibility of CF. Not all children with a positive screening IRT test have CF.What the risks areRisks associated with the test include:Infection (a slight risk any time the skin is broken)Anxiety over false positive testsFalse reassurance over false negative testsSpecial considerationsThe IRT level does not indicate the severity of the CF. False-positives may occur.ReferencesFarrell PM, Rosenstein BJ, White TB, et al. Guidelines for diagnosis of cystic fibrosis in newborns through older adults: Cystic fibrosis consensus report.
