Does the current British royal family carry the haemophilia gene?

No but Juan CarlosII's(Spain) brother was a hemophilliac.His mother was a granddaughter of Victoria and I think a sister to Alexandra the last tsarina of Russia

It is thought that it may have originated with Victoria herself (indeed there were no cases in either of her families of it). It is absent from the present Royal family because The oldest son inherits the throne and he did not have the illness (it's X-linked so sons tend to get the illness whereas daughter only get the illness if their mother is a carrier and their father is a haemophiliac - there is then a 1 in 2 chance). Despite the marrying in of the Royal family (both Queen Mary and Prince Philip are also descendants of Queen Victoria) it has not returned to the British Royal Family. To note: Female Haemophiliacs are incredibly rare, the number in the UK is in single figures. However, their life expectancy nowadays is no worse than a male haemophiliac, with appropriate treatment their life expectancy is no worse (the average is about 10 years shorter than an unaffected person).

No, but porphyria is still around. The Queen and Prince Philip are both related in many ways, principally they are second cousins once removed and third cousins. The queen's cousin William of Gloucester had it.Queen Alexandra (queen's great grandmother) and George of Greece (Philip's grandfather) were brother and sister and THEIR parents were second cousins both descended from George II of England's daughters Mary and Louise-thus our current royal family all descend from George I whose great grandfather was James I whose recorded symptoms were exactly like George III, as were those of his mother, Mary Queen of Scots and her father James.....in fact, earliest records indicate the source may have been John Of Gaunt. His great great grand daughter was Joan the Mad of Spain (sister of Catherine of Aragon) Her recorded symptoms are again very like those of George III. This is why the newest Royals have seen sense and married comoners...

It's still there but it's getting watered down little by little because they aren't intermarrying quite as closely. Though Prince Charles and Princess Diana were 7th cousins!

NO, it was in older days when they were more strict about who you could marry and everyone married first cousins, nieces etc. They can marry a wider range of people now, so genetic diseases are not a factor.

I haven't heard of any recent cases. And 7'th cousins, is barely cousins.

Since there is no intermarrying anymore its probadly dormat.

Not anymore, since they do not inter marry anymore.

they just bleed the british taxpayer

not anymore that back in the days
