Answer 1

Hello friend !!!

Here's the answer you are looking for

Haemophilia is mostly an inherited disease which disables the body's blood clotting process.

Mostly a non-functional parental X Chromosome can cause haemophilia.

So this can be lethal if all the parental X Chromosomes are non-functional.

Therefore the answer according to me is father is haemophilic and mother is a carrier.
