As I said earlier, the Rhesus factor is too complicated to discuss on here.  I was told, when I found out my blood group (Rh A-) that my parents couldn't be my parents, but they definitely are.  I look exactly like my dad and his sisters and my mother definitely remembers giving birth to me!!

I am Rh A- negative and my husband is Rh B+ but all our children are rhesus negative.  One is AB-, another is A-, the others are O-negative.  In simple terms A group is actually AA or AO, B group is BB or BO but it could be that my group is A-O- whilst my husband's (as our children all have negative blood) must be B-O+ or B+O-, it cannot be BB - in any form - or none of our children would be O- and they are, so despite the fact that positive is supposed to be the dominant factor, there was actually more chance of our children ending up Rh negative which some of them did (we have 5).

Read http://rhnegativeregistry.com/rh_negative_rare_and_basic_blood_types.html for a simple explanation.

Slightly off-topic (apologies).

Whilst pregnant my eldest sister was informed she had a rare bloodtype, when she had recovered she was implored to become a donor.
Only one problem, the mere mention/sight of blood sends her queasy and the proximity of a syringe has been known to cause her to faint. :o ;D

Needless to say, she did NOT sign up.

How she survived having three children I will never know! ::)  ;D

Very interesting thread. 
Alone out of 3 siblings I have the B- grouping, and had to have the injection after my first son was born in 1978.

I made my first donation when I was 21, in the crypt of St Martin's in the Fields at Trafalgar Square, London, and have been lucky to remain healthy, so continue to be a regular donor.

Apparently only 2% of the doning population are B- group, which can be used for patients in 4 different groups: B-, B+, AB- and AB+ because of the presence of antigen B, and the absence Rh antigen in my blood.

Hmm. I came across this website while googling DNA and RH - Factor. Someone on here said that it is common along the iberian peninsula and basque people and I've heard this before.

I'm RH- and just did my DNA at ancestry and it says that I am 7% from the iberian peninsula. If anyone on here comes across recent studies about this, please do mention :)

Thanks.

I had my DNA done by a company called 23andMe, which seems to give slightly different results to Ancestry DNA tests, however it shows I am 2.5% Iberian and 2.8% Southern Europe, also 0.1% Asian where Rh Negative is also common.

Interestingly, I am only 42.2% from British & Irish United Kingdom, and the rest from all over Europe, a little Ashkenazi Jewish (which I had guessed) and a bit of Asian.

A chap called Stephen Oppenheimer has written a new paperback on then origins of some of us Brits. You can view his presentation on Youtube at:

The Celts of what is now The Basque Country populated the western fringes of Northern Europe following the end of the last ice age c15,000bp.

There is a brief mention of distribution of blood group B and also Rh -ve alleles. The distributions are not the same and Rh- doesn't share the same distribution/migration as B
