Help needed for my own understanding. (*Hits self with a large stick for leaving work til the last minute*)...

I'm doing 'blood' studies at uni and need a little further clarification...

If a mother with -Rh factor delivers a baby with +Rh, the mother will be sensitized by her babies Rh+ antigens that pass into her bloodstram. If so the mother will form anti-Rh antibodies that can go on to cause problems in later pregnancies by attacking the red blood cell count of the next child.

My qusetion is... :confused:

*If the mother is -Rh, is the +Rh antigen inherited from the father, or is it purely a random occurance?*

hopefully someone can help... i can seem to find the answer anywhere!!

Thankyou :thumbsup:

short answer yes

basically all chromosomes, blood included, come in pairs.
you get one from mum, one from dad.
if mum is negative she has -/- factors in her blood.she can only pass negative factors
if dad is positive, he has +/+ or +/- (positive are dominant). he can pass one or the other.
baby can be either +/- (+ from dad) then be classed as a positive blood type. or baby can be -/- .
as for blood type:
a and b are dominant strains. type a or b parents can be a/a, a/o, b/b or b/o.
type o can only be o/o.
then it works exactly the same as rhesus factors.

does this help??

type o can only be o/o.



Oh wow, so all my children will have 'O' blood type?

Thankyou.. It now makes sense :smiliedance:

Sometimes its hard to interpret the complex textbooks. I find that often it is best to get a 'conversational' answer that's not purely scientific.

Ill have to read it a few more times over to make it 'stick' in my mind.. and i may even print a copy for future references.:idea:

Thankyou VERY much for the help.:wave:

hi oscars mum

all your children will be o/o, if both you and your partner are o/o

if you are o/o, and your partern is for example a/a, then your children will be a/o, making them type 'a', as that is the dominant gene.
but if your partner is type a/o, then your children can be either a/o, or o/o depending on which chromosome they inherit from dad.

does this help or hinder????
