She now thinks she is adopted, but her parents deny it. 4 a. Can they really be her parents? Show Jennifer how it might be possible (if it is) using a Punnet Square.Explanation / Answer
1.a.Because jack parents are O blood group which can give rise to only O type children but jack is an B type blood group
b.blood group types which set for his father would be AB,BB,BO phenotypes which on typing gives rise to B type blood group
2.a.Jills blood group is AB and her parents are A and B blood types
b.parents phenotypes are AO and BO then on typing forms AB,AO,BO,OO by punnet square,but her blood group can't be O so her blood group will be AB
3.a.It's not a good decision,it is possible if both the victims would be BB,BB phenotypes then children would not be suspected,but if the victims has phenotypes either BB,BO or BO,BO then the children will be suspected
b.Yes, the children will be suspected,if parents have their phenotype BB,BO or BO,BO
4.yes,they are her parents,by using punnet square typing of genotypes AO,BO forms AB,AO,BO,OO
5.yes,the babies are exchanged,baby at blues house : AB,OO on typing forms AO,BO,AO,BO
So, the baby at blues house is Type O which doesn't form while typing
Baby at Grays house :AO,AO on typing forms AA,AO,AO,OO ,This baby forms but mrs blue and Mr. Blue can also form .
By, the typing of blues family helps to determine that the babies are exchanged
6.Jeff is not justified,because he also has blood group AB in which genotypes are AB,AB on typing forms AA,AB,AB,AA .So, the baby matches with the blood group typing but Tom and henry can also be suspected.
