These are signs of pneumonia in pregnancy.Subsequently, the infants who are born to such women are feared to have low birth weight and increased preterm birth.
The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotpye is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB.AB blood type is an example of co-dominance since both traits are expressed equally.1  Type A: The genotype is either AA or AO. 2  Type B: The genotype is either BB or BO. 3  Type AB: The genotype is AB. 4  Type O: The genotype is OO.B blood type is an example of co-dominance since both traits are expressed equally. 1  Type A: The genotype is either AA or AO. 2  Type B: The genotype is either BB or BO. 3  Type AB: The genotype is AB. 4  Type O: The genotype is OO.
The rarest phenotypic blood type is Type AB negative found in only 0.7% of people worldwide. Genetically the rarest blood type should be Type O; however, it's the most common blood type. There is more to ABO blood typing that just the ABO gene.There is also an inhibitory gene that will change any genotype into the phenotype O. Therefore a person with genetically AB blood can be tested as having Type O. positive O negative A positive A negative B positive B negative AB positive AB negative The rarest of all these blood types listed is AB negative making up 0.7% of â¦ the worlds population.
