Is Duchenne muscular dystrophy more likely to occur in males or in females?
idk bro why dont you figuhre it out
Who is affected by muscular dystrophy?
Someone whose parent is a carrier of the gene; because the gene is on the X chromosome which is inherited by your mother it would most likely be from her.
How many people have duchenne muscular dystrophy disease?
Around 12% of males die from Duchenne's Muscular Dystrophy
Is the gladiator likely to be skinny or muscular?
Muscular.
Can girl have muscular dystrophy?
The short answer is yes, absolutely. You may be primarily thinking of sex-linked dystrophies, such as Duchenne's or Becker's Muscular Dystrophy. The gene mutations for these types of dystrophy are recessive traits located on the X chromosome. It is vastly more common in boys then in girls because boys only have one X chromosome. If they get the gene for these dystrophies on their mom's X chromosome, then they will not have another X chromosome to "mask" the trait, and thus they will get the disease. Since girls have two X chromosomes, this is a lot rarer. Even if one X chromosome has the gene for the disease, as long as the other one doesn't, they are only a carrier, they don't actually have symptoms. There are only two ways where a girl can get a sex-linked dystrophy: if her mom is a carrier and her dad has the disease, or if her X chromosomes mutate in a way that make her have the gene on both X chromosomes. However: Muscular dystrophies come in dozens of types. Sex linked varieties may be among the most common, but there are plenty out there that are autosomal (i.e.: not sex-linked). Some come from autosomal recessive genes, other come from spontaneous mutations. For those types of muscular dystrophy, girls are just as likely to get them as boys.
Muscular dystrophy?
DefinitionDuchenne muscular dystrophy is an inherited disorder that involves rapidly worsening muscle weakness.Alternative NamesPseudohypertrophic muscular dystrophy; Muscular dystrophy - Duchenne typeCauses, incidence, and risk factorsDuchenne muscular dystrophy is a rapidly-worsening form of muscular dystrophy. Other muscular dystrophies (including Becker's muscular dystrophy) get worse much more slowly.Duchenne muscular dystrophy is caused by a defective gene for dystrophin (a protein in the muscles). However, it often occurs in people without a known family history of the condition.Because of the way the disease is inherited, males are more likely to develop symptoms than are women. The sons of females who are carriers of the disease (women with a defective gene but no symptoms themselves) each have a 50% chance of having the disease. The daughters each have a 50% chance of being carriers.Duchenne muscular dystrophy occurs in approximately 1 out of every 3,600 male infants. Because this is an inherited disorder, risks include a family history of Duchenne muscular dystrophy.SymptomsSymptoms usually appear before age 6 and may appear as early as infancy. They may include:FatigueMental retardation (possible, but does not worsen over time)Muscle weakness Begins in the legs and pelvis, but also occurs less severely in the arms, neck, and other areas of the bodyDifficulty with motor skills (running, hopping, jumping)Frequent fallsRapidly worsening weaknessProgressive difficulty walkingAbility to walk may be lost by age 12By age 10, the person may need braces for walking. By age 12, most patients are confined to a wheelchair.Signs and testsA complete nervous system (neurological), heart, lung, and muscle exam may show:Abnormal heart muscle (cardiomyopathy)Congestive heart failure or irregular heart rhythm (arrhythmias) -- rareDeformities of the chest and back (scoliosis)Enlarged calf muscles, which are eventually replaced by fat and connective tissue (pseudohypertrophy)Loss of muscle mass (wasting)Muscle contractures in the heels, legsMuscle deformitiesRespiratory disorders, including pneumonia and aspiration of food or fluid into the lungs (in late stages of the disease)Tests may include:Electromyography (EMG)Genetic testsMuscle biopsySerum CPKTreatmentThere is no known cure for Duchenne muscular dystrophy. Treatment aims to control symptoms to maximize quality of life. Gene therapy may become available in the future.Activity is encouraged. Inactivity (such as bedrest) can worsen the muscle disease. Physical therapy may be helpful to maintain muscle strength and function. Orthopedic appliances (such as braces and wheelchairs) may improve mobility and the ability to care for yourself.Support GroupsYou can ease the stress of illness by joining a support group where members share common experiences and problems. See muscular dystrophy - support group. The Muscular Dystrophy Association is an excellent source of information on this disease.Expectations (prognosis)Duchenne muscular dystrophy leads to quickly worsening disability. Death usually occurs by age 25, typically from lung disorders.ComplicationsCardiomyopathyCongestive heart failure (rare)DeformitiesHeart arrhythmias (rare)Mental impairment (varies, usually minimal)Permanent, progressive disability Decreased mobilityDecreased ability to care for selfPneumonia or other respiratory infectionsRespiratory failureCalling your health care providerCall your health care provider if:Your child has symptoms of Duchenne muscular dystrophySymptoms worsen, or new symptoms develop, particularly fever with cough or breathing difficultiesPreventionGenetic counseling is advised if there is a family history of the disorder. Duchenne muscular dystrophy can be detected with about 95% accuracy by genetic studies performed during pregnancy.ReferencesKliegman RM, Behrman RE, Jenson HB, Stanton BF. Muscular dystrophies.

Who is more likely to be anorexic females or males?
females
What is the oldest age for a person to live with muscular dystrophy?
In most cases this is diagnosed by age five. In that case the child would need a wheelchair by about age 12. Most likely the child will start to have heart and lung issues by late teens or early twenties. My guess no longer than thirty.
Are kangaskhans only girls?
Kangaskhan can only be females. Most likely because they all have pouches for their children.
Females are more likely than males to have anorexia.?
true, that females are more likely than males to have anorexia.
Are females less likely to become famous?
There is no supporting evidence that females are any less likely or more likely to become famous than males.
Who is affected by a maternal grandfather who is color blind?
it should be the males mostly because males are more likely to become colorblind than females. colorblind females are very rare.
