rhesus negative

[choufleur]

If both mother and father are rhesus negative would the baby definately be negative? was told that there is a 25% chance it would be positive due to grandparent? i'm confused.

I'm pretty sure it's the other way round - if both parents are rhesus positive there is a chance that the baby could be negative (if both parents carry a recessive negative gene).

If both parents are negative the baby would be negative.

I think FertilityFiend is right on this one, if both parents are negative than baby will be negative...

What fertilityfiend said is right, if both parents are rhesus negative, then all your babies will be rhesus negative..

Yep. Negative is recessive.
However, in my first pregnancy, the midwife said she couldn't take my word for it that my DH was the father of my child, and gave me the anti-d anyway . I got a bit more assertive second time around.

i didn't have anti-d either first time around (my midwife believed me fallen madonna) but nurse yesterday at epu said i should have it if i actually turn out to be pregnant and have not miscarried. i didn't think i needed it and thought it was as you said fertilityfriend.

They will always say that you need it if you are rhesus negative, but they cant force it on you.
Im rhesus negative, so I asked them to test my DH to seee if her was rhesus negative or not, but they refused as they wouldnt take my word that he was the father of the baby.
Personally I thought that was up to me to know how sure I was about paternity, not them , so he got tested separately. Unfortunately he was rhesus positive.

dh is definately o-neg and so if DS.

I can understand why healthcare professionals can't just take someone's word for it, because people don't tell the truth about paternity (for obvious reasons!), and the healthcare professionals don't want to risk a future baby's health or even life - Rhesus disease is pretty serious. I worked in molecular genetics for several years researching families with a child with Down's syndrome - we looked at the DNA of families with a child with DS and in about 10% of cases there was a child in the family who was not the child of the 'father' of the family. I think this was quite a high rate and some people probably didn't realise that it was important to tell us the paternity of the children, or didn't want to make an issue of it in front of a step-child, not realising the implications for our research. I think the usual rate is about 5%, so if you were a healthcare professional you wouldn't want to take the chance. .

I do understand that. However, I was completely sure about the paternity of my child and didn't need the anti d. So I declined it in my second pregnancy. Once I had realised that I could actually do so.
