● This `color{Violet}"sex linked recessive"` disease, which shows its transmission from `color{Violet}"unaffected carrier female"` to some of the `color{Violet}"male progeny"` has been widely studied.
● In this disease, a single protein that is a part of the cascade of proteins involved in the `color{Violet}"clotting of blood"` is affected.
● Due to this, in an affected individual a `color{Violet}"simple cut"` will result in `color{Violet}"non-stop bleeding"`.
● The `color{Violet}"heterozygous female"` (`color{Violet}"carrier"`) for haemophilia may transmit the disease to `color{Violet}"sons"`.
● The possibility of a `color{Violet}"female"` becoming a `color{Violet}"haemophilic"` is extremely `color{Violet}"rare"` because mother of such a female has to be at least carrier and the father should be haemophilic (unviable in the later stage of life).
● The family pedigree of `color{Violet}"Queen Victoria"` shows a number of `color{Violet}"haemophilic descendents"` as she was a carrier of the disease.
