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.
In sex-linked inherited diseases such as hemophilia, mothers most often pass the disease to sons.
Yes, as in only males can have hemophilia.

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.
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.
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.
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.
no
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.
It is actually not possible to 'get' hemophilia. Hemophilia is passed on from the mother (the carrier) to the son, not the daughter as it is rare for a girl. A boy has two chromosomes, an X and a Y, and girl has two X's. Hemophilia is inherited through the X chromosome, so a girl can carry hemophilia, but unless she inherits hemophilia on both of her chromosomes, she can't have the disease. REGARDING YOUR QUESTION, It is actually not confirmed whether Lincoln had hemophilia, people suspected some sort of genetic disorder, there were two suspected and hemophilia was one. People didn't know very much of the disease when Abraham was president. In fact is wasn't a named disease until 1828, and then hemophiliacs often didn't live pass the age of thirteen. With not much doctors could do to stop bleeding, and considering the age of Abraham its unlikely he had hemophilia.
