Males have one X chromosome and one Y chromosome while females have 2 X chromosomes. Thus wen a son is born, he inherits his father's Y chromosome and one of his mother's X chromosomes. Since the trait for hemophilia is located on the X chromosome, it must either be passed down from the mother or result from a spontaneous mutation.

What is a carrier for hemophilia?
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.
Can xHxH be hemophillia?
Yes, xHxH can represent a female carrier of hemophilia, where "H" denotes the hemophilia allele and "x" denotes the normal allele. In this case, the individual has one normal allele and one allele for hemophilia. However, a female carrier typically does not exhibit symptoms of hemophilia but can pass the allele to her offspring. Males with the genotype "xHy" (where "y" is the male chromosome) would express the condition due to having only one X chromosome.
Why is it unlikely that natural selection will quickly reduce the frequency of hemophilia?
While the condition affects the males, it is CARRIED by the females, who do not suffer the effects of hemophilia, and can pass the disorder to THEIR female offspring.
What is a true of sex linked inherited diseases such as hemophilia?
Yes, as in only males can have hemophilia.
A woman is a carrier for hemophilia what are the chances for sons with hemophilia if the father does not have hemophilia?
Since the gene for Hemophilia is carried on the X chromosome and males pass only their Y chromosome onto their sons, no their sons should not have hemophilia. Of course all daughters of a male with hemophilia will be carriers of the mutation since they with receive his X chromosome, not the Y.
Which of the parents can pass the allele for hemophilia to a daughter?
The father is the one who can pass the allele for hemophilia to a daughter. Hemophilia is a recessive X-linked disorder, so the daughter would need to inherit the hemophilia allele from her father.
Are some boys carriers for hemophilia?
A male with hemophilia does in fact carry the genes and can pass them on to his daughters, so yes, some boys (if they have hemophilia) are carriers.
Is it true that fathers most often pass hemophilia to sons?
Partly true, but the girls carry the disease, they usually don"t have it. Hemophilia among women is rare, but does occur. We were so close there was no room, but Only Stacy was immune! ( parody on Melanie song Lay Down) It is obviously about the St. Petersberg massacre.
Is hemophilia due to heredity?
Yes hemophilia is a inheerited bleeding dissorder. i read it from my medical book. hemophilia means blood love and can be passed down from mother to daughter. or in some cases mother to son. it is more common for it to passed to daughters. I hope this helped. :)
What is Sex - linked inherited diseases such as hemophilia?
In sex-linked inherited diseases such as hemophilia, mothers most often pass the disease to sons.
If you have hemophilia what are the chances of giving it to your kids?
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.
What is true of sex linked inherited diseases such as hemophilia?
In sex-linked inherited diseases such as hemophilia, mothers most often pass the disease to sons.
