Sam has hemophilia. Sam’s brother, mother, and father do not have hemophilia. Draw a pedigree showing who has the disorder and who is a carrier.
A carrier for hemophilia is a female who carries the genetic mutation for hemophilia on one of her X chromosomes, but does not exhibit symptoms of the condition herself. Carriers can pass on the gene mutation to their children, resulting in hemophilia in male offspring. Testing can confirm carrier status.
Hemophilia is a X linked recessive disorder. Usually the mother is an unaffected carrier and her son unfortunately receives the X chromosome in which hemophilia is linked to.
Yes. Mostly males. It is exceedingly rare for a woman to acquire hemophilia(unless she is a carrier of it). Women have a diminutive chance of having this genetic disorder.
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.

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.

If you mean "how is it PASSED on", then.... Hemophilia is passed down from mother to son through your genes. 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 Two: Mother(Non-Affected)+Father(Hemophiliac)=All sons will be non-affected and all daughters will be carriers. If you really meant "how it is pasted on", well...hemophilia is a genetic disorder. You can not "glue" or "paste" it to anything. Sorry to disappoint you... :)
hemophilia is a recessive gene, if you are A female that is a carrier then if you were to have a male child it will be passed on to him. As well as if you were to have a male child who would have hemophilia. your daughter would need to be tested to see if she carried it as well. Only Males have hemophilia but females carry it.My family has dealt with hemophilia for years.My great Aunt carrier, her son has hemophiliaMy mother a carrier, my brother has hemophilia, I do not carry it.My Aunt is a carrier, my cousin he has it, his sister carrier as well.The scientific answer isThis is due to the fact that females have two X chromosomes while males have only one, lacking a 'back up' copy for the defective gene the defective gene becomes manifest more easily in males. Because females have two X chromosomes and because haemophilia is rare, the chance of a female having two defective copies of the gene is very low, thus females are almost exclusively asymptomatic carriers of the disorder.
