Hemophilia is a Sex-linked genetic disorder. It is found on the X chromosome of chromosome 23.A carrier for Hemophilia(represented by H(dominant) or h(recessive)) would look like this:XHXh(Female)*Males are not carriers for hemophilia-They are either affected or they're not*An affected person would look like this:XhXh(Female) XhY(Male)Someone who is neither a carrier nor affected would look like this:XHXH(Female) XHY(Male)
The blood is affected. The blood of a person with Hemophila lacks the clotting factor, so people with it are "Free Bleeders."
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".
Hemophilia is actually the lacking of specific proteins in the blood. The liver normally produces these proteins (called clotting factors) but in people with hemophilia it does not function normally, either not producing or produces non funtioning versions of one or more of these clotting factor proteins
Hemostasis means control of bleedingit is constant internal chemical composition
If both parents have x-linked hemophilia, the father's genotype would be XhY and the mother's genotype would be XhXh, which is astronomically rare. If this did happen, all of their children would inherit x-linked hemophilia. Hemophilia is passed down from mother to son. It is extremely rare for a woman to have hemophilia. It is necessary, though, for a woman to be a carrier of the disorder for her son to acquire this disorder. Females have two X chromosomes whereas males only have one. When a boy is born, he takes one X chromosome from his mother and one Y chromosome from his father. Therefore, he can only get hemophilia through his mother. Example One: Mother(Carrier)+Father(Non-Affected)=50% chance of their son acquiring the disorder and 50% chance of their daughter being a carrier. Example Two: Mother(Non-Affected)+Father(Hemophiliac)=All sons will be non-affected and all daughters will be carriers.
Males only have one copy of the X chromosome
Primary hemostasis is the overall sequence of events that leads to the formation of a platelet plug, while Secondary hemostasis is the signal transduction pathway that leads to the formation of fibrin. Secondary Hemostasis is always a part of Primary hemostasis, but involves many clotting factors and other signaling molecules that are specific to the formation of fibrin
Hemophilia A is an X-linked, hereditary bleeding disorder caused by the absence or defect of a blood clotting protein, Factor VIII. As a result, when a person with hemophilia A has a bleeding episode, the bleeding may be prolonged due to the body's inability to form blood clots. Patients who are affected with hemophilia A experience frequent spontaneous bleeding, most commonly into their joints and soft tissues, with bleeding into vital organs that may ... be life-threatening. Bleeding episodes may be painful, and over time, recurrent joint bleeding may result in debilitating destruction of the joints. Currently, patients with hemophilia A are dependent on injections of Factor VIII produced by genetic engineering or purified from human plasma, to help control a bleeding episode. It is estimated that approximately 50,000 individuals worldwide are affected with hemophilia A. Hemophilia A - Clotting Factor VIII Hemophilia B - Clotting Factor IX Hemophilia C - Clotting Factor XI
You would get it from your mother. It is a sex-liked genetic disorder. Females are the carriers, males exhibit the condition.
