Answer 19

Nearly 80%

Question 20

How can an individual be RH positive and RH negative

Answer 20

If the person contains more than 80% of RH antigen on the surface of RBC, they are RH positive and if this antigen is absent, they are RH negative

Question 21

What is the condition seen in erythroblastosis foetalis?

Answer 21

This is a type of incompatibility between the RH negative blood of a pregnant mother with RH, positive blood of the foetus, RH antigen of the poet do not get exposed to the RH blood of the mother in the first pregnancy as the two bloods are well separated by the placenta. However, during the delivery of the first child, there is a possibility of exposure of the maternal blood to small amounts of the RH positive blood from the foetus In such cases, the mother start preparing antibodies against our age antigen in her blood. In case of her subsequent pregnancy, the RH antibodies from the mother RH negative can leak into blood of the RH positive and destroy the foetal RBC, this could be fatal to the foetus or could cause severe anaemia and jaundice to the baby
