Is it possible to have the same blood type as a particular parent but a different rhesus factor?

Absolutely...they are different types of antigens, and are codified by different parts of the genoma...we can have any combination of blood type with the presence or not, of the glycopropein Rhesus (Rh)----- One proprety of the blood erythrocytes ha nothing to do with the other,,,,


So yes, we can have positive Rh or negative Rh combined with any blood type (O, A, AB or B)Is it possible to have the same blood type as a particular parent but a different rhesus factor?
yes it isIs it possible to have the same blood type as a particular parent but a different rhesus factor?
yes If your parents are both Rh+ and you are Rh-


or your one of your parent is Rh- and another is Rh+





Rr * Rr ---%26gt; 1/4 RR + 1/2 Rr + 1/4 rr


rr*Rr----%26gt; 1/2 Rr + 1/2 rr





r for Rh-


R for Rh+ and dominant





Rh is in-depend from blood type
Yes, here's how:





Rh factor is either + or -.


A person has two genes.


If they have ++, then they are + (Rh positive).


If they have +-, they are also +.


But if they have --, then they are - (Rh negative).





If one parent is ++ and the other parent is --, the child will be +- (the same as one parent, but different from the other).





If one parent is +- and the other parent is --, the child may be either +- or --. (Again, the same as one parent, but different from the other).





If both parents are +-, there's a 25% chance that the child will be --. (different from either parent)





My wife and I are +-. We have one child who is -- and one child who is +? (there's no way short of genetic testing to tell whether that child is ++ or +-.)





It is possible for two Rh+ parents to have an Rh- child.





However, it is impossible for two Rh- parents to have an Rh+ child. They can only have Rh- children.
Yes, particularly if that parent is a male.
Yes
Yes, most definitely. If both parents, for instance, are rhesus positive and they have rhesus negative in their genetic makeup and on conception the two negatives meet, the child should be born with the negative factor, but one of the parents blood groups. I am A neg, my mum was A pos and my dad was O pos. It was not discovered until the early 1970's, hence the paternal blood testing they did prior to this became obsolete and ceased to be of any relevance as all it did was ';supposedly'; state whom the father could not be.
