I just came across a statement in my book , while reading genetics, that haemophiliac females do not survive till birth (the reason not mentioned here why) . Before posting this question here I conducted quite a bit searching on the net but couldnt find any document on this. Can anyone tell me the reason why don't haemophiliac foetus make till birth ? I mean where is the problem, when a haemophiliac male having XhY can survive why not an XhXh female ? enter image description here

    $\begingroup$ Please refer to a standard book on genetics. From CDC website: Females can also have hemophilia, but this is much rarer. In such cases both X chromosomes are affected or one is affected and the other is missing or inactive. In these females, bleeding symptoms may be similar to males with hemophilia. $\endgroup$ – WYSIWYG Mar 2 '15 at 17:15

    $\begingroup$ I also think this question should remain open. It doesn't match any of the close reasons, is narrowly scoped and perfectly answerable. We address incorrect information all the time, that's one of the reasons this site is here. $\endgroup$ – MattDMo Mar 3 '15 at 15:54

Haemophiliac females are rare but they can survive just like affected males do. However, the case is slightly more complicated in women because of menstruation.

I could not find an article from any medical journal but this site seems authentic enough for a reference.
