Could two phenotypically normal parents have a child with Hemophilia A?
XhXh - with hemophilia XhXH- carrier of hemophilia
A recessive gene located on the X chromosome is the cause of hemophilia in affected individuals. Males are more likely to have hemophilia than females because?
Males only have one copy of the X chromosome
Is it possible for a female to be a carrier of hemophilia?
Hemophilia normally refers to a genetic disorder that can be either inherited or the result of a spontaneous mutation. Since the genetic form of hemophilia is linked to a mutation on the X chromosome, males typically show the full symptoms while females with the mutation typically have somewhat mitigated symptoms or none at all. While the majority of the cases of genetic hemophilia are inherited, meaning that the genes were passed down from the the parents, approximately 1/3 of the cases are spontaneous mutations. The mutation occurs at conception, meaning that all genetic forms basically take effect at birth. Acquired hemophilia is a result of some other influence such as liver damage or specific medications. This form of hemophilia is neither inherited nor genetic. In short, technically anyone can get hemophilia. Genetic hemophilia is present at birth, and it tends to impact the health of males more than females, but can affect females too.
Can a genetic disease affect anybody?
Exceptions are always there e.g hemophilia and many bleeding disorders don't affect females.
Why are sex-linked recessive disorders such as hemophilia are most often seen in mails and rarely seen n females?
This 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 hemophilia 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. It is very rare for a female to have hemophilia
Why are females less likely to get hemophilia?
Females are less likely to show the symptoms of hemophilia but in actuality are more likely to have the genetic mutation for hemophilia. The reason they are less likely to show the symptoms is the fact that hemophilia is the result of a mutation on the X chromosome. Since females have two X chromosomes they likely have a chromosome that is not mutated as well. With the mutation normally being a recessive trait, the normal X chromosome is usually expressed instead. Since males only have one X chromosome, if the mutation for hemophilia is present, it will be expressed. For the same reasons, the chances of a female having the mutation is greater (however still very small), simply because she has two X chromosomes.
How many alleles for hemophilia do females have?
females have 2 alleles for hemophilia, (X^hX^H) and (X^hX^h) if H is the normal allele and h is the recessive allele for hemophilia
Why is hemophilia more common in males than in females?
The genes associated with Hemophilia A and B are located on the X chromosome, which is one of the 2 sex chromosomes. For males, who have only 1 X chromosome, 1 altered copy of the gene in each cell is sufficient to cause hemophilia. In females, who have 2 X chromosomes, a mutation would have to occur in both copies of the gene to cause hemophilia. Since it is unlikely that females will have 2 altered copies of this gene it is therefor very rare for females to have hemophilia.
Why is there a difference in the numbers of alleles for hemophilia and colorblindness between males and females?
females have xand males dont
Can a girl have hemophilia?
Yes females can have hemophilia. Although very rare it has been recorded. A female can get hemophilia if her mother is a carrier and her father has it. Like I said, It doesn't happen often but is possible.
Why Hemophilia more common in male than in female?

Could a Girl have hemophillia?
Yes. Hemophilia is sex-linked, and is much more common in males than in females, but it is not impossible for a girl to have hemophilia.
Could two phenotypically normal parents have a child with Hemophilia A?
XhXh - with hemophilia XhXH- carrier of hemophilia
Why are men most likely to have hemophilia then females?
cus i say so ahahahahah
Why is hemophilia considered to be a sex link trait?
Because the gene that causes hemophilia is located on the X chromosome, so it will occur in males more frequently than in females.
Why males are afflicted with hemophilia more than females?
Because males have the chromosome XY. And Hemophilia attacks the X chromosomes, so if the disorder gets to the X chromosome of the male, it doesnt have another X chromosome to back it up like females do.(XX)
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.
