a recessive X-linked genetic disorder, the mutation that causes hemophilia is passed to offspring via the X chromosome. Hemophilia is more common among male children because they only inherit one X chromosome.

Answer:
Haemophilia is a sex chromosome. It is a recessive disorder and it has its genes present on the X chromosome. Male chromosomes are XY and female chromosomes are XX. In males have only one X chromosome, the Y chromosome do not have any counter genes. So, the chances of males getting affected are more. For a female to get affected both the X chromosomes must contain the affected genes, which is a very rare case.
