A couple quarrelled with the hospital authority on suspicion that their child had been exchanged after birth.The couple based their argument on the fact that their child is O blood group and they are A and B blood groupsrespectively.The doctor smiled and explained:
- How can the child be O blood group explained by the doctor?
- Which test method can be considered authentic to identify the biological parents?
- Write steps of this method.
1. the blood group of parents are:
father: i^A i mother: i^B i.
possible blood group of offspring: i^A i^B or i^A i or i^B i or i i.
its found that the child's blood group is O, i e. i i
the doctor can explain them about ABO- blood grouping.
2. the most advanced method for biological testing is PCR or polymerase chain reaction method (you'll read about it in Biotechnology: principles and processes).
3. the three steps involved in PCR :
denaturation, anneling , extension.
father: i^A i mother: i^B i.
possible blood group of offspring: i^A i^B or i^A i or i^B i or i i.
