antigens present in the red blood cells
of the donor and the antibrecipient can produce. Whenever theodies that th e
recipient is not able to produce
antibodiblood cells of the donor the transfes against antigens of the redusion (^)
is compatible.
So regarding ABO comcan donate to type A and to type patibility type AAB.
Type B can doAB. Type AB can nate to type B and to typedonate only to type
AB. Type O can donate to all ABO types.
(Blood transfusion must be studied,
planned and supervised by doctors.)
- What are universal donors
and universal recipients
concerning the ABO blood
system?
Universals dosystem are the individuals of the typenors of the ABO blood type
O. Type O blood does not have antigA neither antigen B in its red blood cellsen (^)
and can ABO type.be donated to individuals of any
Universal rtype system are ecipients of the ABO bthe individuals of thelood (^)
type AB. Type AB blood does not
contain antibody anti-A nanti-B and people of this group caneither antibo dy
receive blood from any of the ABO
types.
- What is the type of genetic
inheritance that determines
the ABO blood group system?
What are the relations of
dominance among the
involved alleles?
The inheritance of the ABO blood
system isThere are three involve a multiple alleles id alleles, Inheritance.
and i that combine in pairs to form thA, IBe^
genotypes.
Concerning dominance, recessive in relation to the alleles Ithe allele i is
IB. Between IA and IB however lack ofA and
dominance is establisheheterozygous (I d with the

respective blood types of the
ABO system?
Since the alleles arpossible genotypes are Ie IA, IB and i the

investigation of natural
paternity, maternity or
brotherhood and sisterhood
using the ABO blood typing?
By usinpossible og the ABO bnly to exclude paternity,lood typing it is
