Hemophilia is sex linked. Males inherit from their mother, daughters are carriers if the defective gene is inherited from one of either parent. A female must inherit two copies of the defective allele to have hemophilia .
Anyone can inherit hemophilia. In most cases, it is a man whose mother is a carrier of the disease. It is extremely rare for a woman to have hemophilia but it is not uncommon for one to be a carrier. It is even possible for someone whose family has no record of hemophilia to get it through gene mutations.
Male hemophiliacs inherit it from their mother, because hemophilia is only on the X gene and males only have one and it is from their mother.
Because the condition is an error on the X chromosome of the XY pair and the Y comes form the father and the X the mother.
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".
It is a sex-linked recessive trait inherited from the mother.
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.
Possible blood types are A, B, or AB. Basically, the offspring can be any blood type except for O.
In human being and other mammals offspring inherit approximately 50% genes from mother and 50% from father .
If the father has hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of having hemophilia and a 50% chance of being a carrier. It is very rare for both parents to have these defective genes.If the father does not have hemophilia and the mother is a carrier, sons will have a 50% chance of having hemophilia. Daughters will have a 50% chance of being carriers.If the father has hemophilia and the mother has normal blood, all sons will be normal and all daughters will be carriers.
Mary's father is normal and has a normal genotype XY while her mother is the carrier of hemophilia and has one X of her genotype infected i.e. she is X*X.
The gene for hemophilia is found on the 'X' human chromosome. However it is a recessive gene so if a woman (who has two 'XX' chromosomes) has one bad 'X' and one good 'X' she will not have hemophilia but will be a carrier .If she has female children and their father is not a hemophiliac, then half of her daughters may carry the bad 'X' chromosome but non will manifest the disease.However, if her children are male then her sons will have an 'X' chromosome inherited from her and a 'Y' chromosome inherited form the father and there is a 50% chance that the 'X' chromosome inherited will be the bad one. If the son inherits the bad 'X' he will be a hemophiliac and if he lives to father any daughters then all these daughters will be hemophilia carriers (because they must inherit his (bad) 'X' chromosome).It is possible for a woman to manifest hemophilia if the mother is a carrier and the father is a hemophiliac. In this case it is possible for a daughter to inherit the bad 'X' from the father and the mother's bad 'X' giving the daughter two bad 'X' chromosomes.
it means that you inherit this form of disorder either from your mother or father's sex chromosomes. For example- color blindness or Haemophillia.
