In a maternity ward, four babies become accidentally mixed up. The ABO blood types of the four babies are known to be. Baby Jane
nydimaria [60]

Answer:

See explanation

Explanation:

We inherit our blood groups from both parents. Our blood type is controlled by a single gene. This gene displays 3 different allelic pairs which must include A, B or O.  A child is expected to receive one of the three possible allelic pairs from each of the both parents. This means that there are six possible genotype and four possible phenotype for the child.

Given that Christopher's parents (Andersons) are AB and O,Christopher can have a B blood group.

Given that John's parents (Browns) are A and O, it explains how John can have blood group A.

Given that The Christiansons are A and AB, they can give birth to Robin whose blood group is AB.

Since the Dietrichs are O and O, the only possible blood group of their child is O, hence they are definitely the parents of Jane.
