Explain What Is Natural Selection What Does It Do To Deleterious Genes

Cystic Fibrosis is an inherited condition. However, the gene for Cystic Fibrosis is recessive and

Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

In infants symptoms include coughing, wheezing, excess mucus in the lungs, shortness of breath, extremely salty skin and decelerated growth. With infants it is very common for them to develop pneumonia infections because of all the bacteria that resides in the lungs. With treatment, most patients with cystic fibrosis live into their 20’s and 30’s, some individuals with milder cases can live longer. Death is most often due to end-stage lung disease.Thus far no cure for the disease has been found. Although, research on gene therapy is promising. Treatment is generally aimed at alleviating symptoms, preventing infections, and slowing the progress of the disorder. (Egan’s 10th Ed,

Cystic Fibrosis, also known as CF, is one of the most common life-threatening genetic disorders found in people. Discovered in 1938 by Dr. Dorothy Hansine Andersen, Cystic Fibrosis severely affects two parts of the human body, including the respiratory system and the digestive system. Cystic Fibrosis causes the mucus glands to secrete very thick and sticky mucus. This mucus then clogs the tiny air passages and traps bacteria in the lungs. The thick mucus also stops the release of digestive enzymes in the pancreas from reaching the small intestine. According to Cystic Fibrosis Queensland (2015) more than one million Australians carry the Cystic Fibrosis Gene, with one in every 25 people, often not realising they are carrying the deadly gene.

The goal of natural selection is to promote healthy genes that enable us to survive. Natural selection weeds out harmful genes that make us weak.

Cystic Fibrosis is a genetic disease which is progressive and limits breathing ability. The lungs and other organs are affected by a thick buildup of mucus. This mucus traps bacteria which leads lung damage, infections, and respiratory failure. The digestive enzymes being released is prevented, affecting the breakdown of food and nutrients being absorbed. ?More than 30,000 children and adults in the United States have Cystic Fibrosis. 70,000 people worldwide.? (Diagnosed With Cystic Fibrosis, Cystic Fibrosis Foundation) Someone who has Cystic Fibrosis have a defective gene from each parent which produces faulty protein. The CFTR gene is the gene that is mutated causing this. The channel that transports chloride in and out of cells is created by instructions that are created by CFTR gene. The regulation of chloride ions and water are prevented creating the thick mucus formed on the passageways of lungs, pancreas, and other organs. Cystic Fibrosis doesn?t cause learning problems are mobility of the person. Babies with this still develop and grow up normally. The average life expectancy is close to 40 years, and has been increasing in the last fifty years thanks to improved care. ?Chronic coughing, recurring chest colds, wheezing, shortness of breath, frequent sinus infections, and allergies that last all year, are the most common symptoms of Cystic Fibrosis.? (Cystic Fibrosis Symptoms) Since this disease is progressive

Nausea and loss of appetite, and weight loss. There are also a lot of symptoms if you have Cystic Fibrosis in you lungs and respiratory system such as coughing or increased mucus in the sinuses or lungs, fatigue, nasal congestion, repeated episodes of pneumonia, fever, increased coughing and shortness of breath, increased mucus, loss of appetite, and sinus pain or pressure caused by infection or polyps. Also with Cystic Fibrosis you could only experience symptoms later in your life like infertility (in men), repeated inflammation of the pancreas, respiratory symptoms, and clubbed fingers. One general symptom of Cystic Fibrosis is salty tasting skin. The treatment for Cystic Fibrosis is fairly mild with only treatment through antibiotics, inhaled medicines to clear the airways, a lung transplant in extreme cases, and oxygen therapy if a lung infection becomes really bad. Treatment for Cystic Fibrosis that impacts your digestive system is also pretty mild. It can be treated with a special high protein and high calorie diet, ingestible pancreatic enzymes, and vitamin

Cystic Fibrosis affects 1 in every 2,500 children at birth. (ncbi.nlm.nih.gov) Cystic Fibrosis, or CF, is a genetic disorder. A genetic disorder is inherited, and is contributed to by both parents. (lung.org) Each parent has one abnormal gene. (lung.org) Cystic Fibrosis is where the body can not make, or it makes an abnormal version of the CFTR protein. CFTR is also known as cystic fibrosis transmembrane regulator. There are several symptoms, and causes of Cystic Fibrosis. These symptoms are diagnosed, according to what causes CF. Cystic Fibrosis is an inherited disease, that when after diagnosed, doctors will suggest treatments to help with the condition. Cystic Fibrosis is most common in white infants, but can

Cystic fibrosis is a disorder that causes severe damage to the respiratory and digestive system. (Saint Francis Medical Center) It is caused by an inherited defective gene from both parents, specifically the CFTR gene, which causes the cells to overproduce mucus, digestive juices, and sweat. Normally, the fluids that are secreted are slippery and thin. However, with cystic fibrosis, the defect in the gene causes thick and sticky secretions. Instead of the secretions having lubricant properties, it clogs up tubes, passageways, and ducts, especially in the pancreas and lungs.

The symptoms of cystic fibrosis are salty-tasting skin, persistent coughing (sometimes with phlegm), Lung infections that are frequent, shortness of breath, constipation, and male infertility. Some examples of lung infections are pneumonia and bronchitis. If you have Cystic Fibrosis, you’re mucus becomes sticky and thick, and blocks your airways and becomes built up in your lungs. All of the extra mucus build up makes it much easier

Minimizing contact with germs is a top concern for people with CF. The buildup of mucus in the pancreas can also stop the absorption of food and key nutrients, resulting in malnutrition and poor growth. In the liver, the thick mucus can block the bile duct, causing liver disease. In men, CF can affect their ability to have children. Most people diagnosed with cystic fibrosis today are babies, thanks tonewborn screening programs. More than 75% of children with cystic fibrosis get a diagnosis by age 2. In some cases, people don’t find out they have cystic fibrosis until they’re teens or adults. Parents can also test their babies for cystic fibrosis before they’re born. Cystic fibrosis is a serious disease that can be life-threatening. But it’s different for everyone. Symptoms are mild for some people and severe for others. The good news is that most people with cystic fibrosis now live twice as long as they did 30 years ago. Today, some people are living into their 40s, 50s, or longer. Cystic fibrosis has no

Cystic Fibrosis can cause problems in the reproductive system. Cystic Fibrosis patients have many more sexual reproduction problems than a healthy human. In males with CF, they are likely to be infertile because of the tube connecting the testes and the vas deferens is missing or blocked with mucus. In women with CF, pregnancy can be a lot more difficult. Pregnancy can worsen the symptoms of Cystic Fibrosis. Women with CF may also be less fertile than women without CF. Women with CF should always consult with a doctor to know all of the possible risks. In order to get CF, both partners must be a carrier because the CF gene is recessive. If someone is a carrier, they could pass it on to their own child. Cystic Fibrosis tends to run in families, since it is an inherited disease. It is also most common in Caucasians.

Cystic fibrosis is a genetic disease that affects the respiratory system, digestive/endocrine, and reproductive system. A defective gene produces an abnormally thick mucus in the trachea and causes a blockage in the trachea, damages lung, and resulting in failure of the respiratory system. The mucus also interferes with the pancreas, which it prevents the secretion of digestive enzymes that help dissolve food, causing difficulty in absorbing nutrients. CF causes infertility, particularly in men. However, they are not sterile, therefore they can have children with assisted reproductive techniques. In most cases, many of them are diagnosed with CF before the age of 2 because the newborns are screened immediately after birth. On the other hand,

Cystic fibrosis is an inherited life- threatening disorder that damages the lungs and digestive system. This disorder can also be known as Mucoviscidosis . Long- term issues include difficulty breathing, also coughing up sputum as a result from frequent lung infections. Sinus infections, poor growth, clubbing of the finger and toes, also infertility in men are other possible symptoms of this disorder. Different individuals may have different degrees of symptoms. Cystic fibrosis is an autosomal recessive disorder. Mutations in both copies of the gene for the protein cystic fibrosis transmembrane conductance regulatory (CFTR) is the cause of this. CFTR is involved in production of sweat, digestive fluids, and mucus. Secretions,

Cystic Fibrosis is a disease that affects the body in many ways throughout the patient's life. Newborns with Cystic Fibrosis may experience delayed growth, inability to gain weight, and salty-tasting skin ("Cystic," umm.edu 1). Older patients may be infertile, have recurring pancreatitis, and respiratory problems ("Cystic," umm.edu 2). Considering that these are just symptoms involving age, the full spectrum of ailments that afflict a patient with Cystic Fibrosis is far more taxing on a patient.
