heamophilia is a disease in people which makes your blood go weird :)
it is a genetic disorder where the person lack of clotting factor in the blood. A person with haemophilia will have trouble with bleeding because the bleeding wont stop due to the lack of blood-clotting factor.

One type of genetic bleeding disorder?
Heamophilia
Heamophilia is an example of what?
An X-linked genetic disorder.
How does heamophilia affect the body?
Something with the brain. I believe it impairs your ability to perform certain tasks.
How is heamophilia treated?
The main course of treatment for hemophilia is replacement therapy. Via IV drips, clotting factors and added to the low or missing clotting factors detected in the patients system.
What is diet for heamophilia a patient?
While no special diet is recommended for people with hemophilia, the basic concepts of good eating still apply. Eat healthy and avoid junk food. Note that teens and children with hemophilia are almost twice as likely to be overweight as the same age group in the general population. Therefore they should make an added effort to maintain a healthy weight.
How is heamophilia inherited?
The gene for haemophilia is located on the X chromossome, and can be passed by haemophiliac or carrier mothers to sons (more common) or daughters. Haemophiliac fathers will always have carrier (but not necessarily affected daughters.)
Why is haemophilia a lethal gene in its homozygous state?
Heamophilia A is caused by an impairment of a protein (clotting factor VIII deficiency) which is used to prevent clots. It is also used to produce fibrin, which is used in platelet activation. Without platelets, cellular differentiation is severely limited, leading to pre-natal death.
Which parent passes parkinsons disease?
A parent may only pass the gene for Huntington's if they HAVE Huntington's. It is transmitted on a Dominant gene. If you do not HAVE Huntington's. it is not possible to pass it to your children. My wife inherited the gene from her father. Our sone and daughter inherited from their mother. It can be from either parent, but only if that parent has HD.
How do you treat heamophilia?
Standards of care for Hemophilia vary greatly around the world and from one doctor to another there are variations of care. Most doctors agree treatment of Hemophilia is administration of anti-hemophiliac factor. The main treatment for hemophilia is called replacement therapy. Concentrates of clotting factor VIII (for hemophilia A) or clotting factor IX (for hemophilia B) are slowly dripped in or injected into a vein. These infusions help replace the clotting factor that's missing or low.
What are the symptoms of heamophilia?
The following are symptomatic of haemophilia:Very easily bruisedProlonged nosebleedsExcessive bleeding from biting down on the lips or tongueExcessive bleeding following a tooth extractionExcessive bleeding following surgeryBlood in the urine (called hematuria)Bleeding in the knee, elbows, and other joints (appears as joint swelling that feels warm to the touch and normally causes weakness and stiffening of the joint)Bleeding in the brainCuts seem to bleed longer than normalArthritic joints at young ageBear in mind that Haemophilia is a basically a genetic disorder, you have to inherit it, you cannot catch it (although people with severe liver damage can present symptoms of haemophilia); as it is inherited, the chances are you would know that you are already predisposed to the mutation.
What is Red green color blindness and hemophilia are two human genetic disorders that are caused by a what?
Color blindness is a sex-linked genetic disorder. The reason that it is more prevalent in males is because the disorder is linked the the X-chromasome. If a male inherits an X chromosome that is defective, then they will be color blind. However, a female has two X chromosomes which means she can receive a defective chromosome and only be a carrier of the mutation. If she receives two defective x chromosomes, she will be colorblind.
Are dominant or recessive alleles easier to remove by selection?
Natural selection favors whatever allele provides a selective advantage, so in theory it can operate on either. However, if a recessive allele provides an advantage it will soon shift and become the dominant allele, so it could be argued that natural selection favors dominant alleles. This is only partly true. A dominant gene always has some effect on the characteristics of the organism, even if the owner only has one of them. A recessive gene only affects the characteristics if there is no equivalent dominant gene to mask the effect. If both parents possess the recessive gene there is a chance the offspring will have two of them and this will show in their characteristics. When this happens, natural selection operates on the recessive gene. Much of the time, a recessive gene is present but natural selection does not affect it because there is a dominant gene that masks the effect. If natural selection favours the recessive gene, the dominant gene will quite quickly disappear from the population. This does not make the recessive gene 'dominant' it's just tht there's no longer any competition. If selection favours the dominant gene however, the recessive gene can linger in the population for much longer, because even when it is present, it is not selected against for most of the time. That is why conditions like heamophilia survives for a long time in humans, and you suddenly discover a white deer after many years in a herd of brown deer.
