Question

explain if the were switched at birth? The situation pertains to switching of babies and how to determine if there was a switch using ABO blood typing procedures. In order to determine the possible blood types of the offsprings, the blood type of the mother and father must be tested. Please see example below: You have to test the blood type of all concern persons in order to determine if there was a switch of babies. By following the example above you can determine the answer to the situation. Mary B Anti-A-no agglutination; Anti B-with agglutination Michael AB Anti-A-with agglutination; Anti-B-with agglutination Emily B Anti-A-no agglutination; Anti-B-with agglutination Ernest A Anti-A-with agglutination; Anti-B-no agglutination Emma O Anti-A-no agglutination; Anti-B-no aggllutination Michael Jr. B Anti-A-no agglutination; Anti-B-with agglutination Michelle A Anti-A-with agglutination; Anti B-no agglutination Mary and Michael possible offsprings: AB, AO, BB Emily and Ernest possible offsprings: AO, BO, OO Conclusion: No switch of babies

Answer 1

Given:

Parents:

Mary X Michael: BO x AB

Emily X Ernest: BO x AO

Babies:

Emma: O ---> 100% chance that she is the child of Emily and Ernest. To have a blood type O, both parents should possess the allele O.

*Michael Jr: B

*Michelle: A

* They are the twins because Mary and Michael's offspring could only have the following genotypes: AB, AO, BB, BO. Therefore, they could not produce a baby with blood type O.

ANSWER: There is no baby switch. The possibility of Mary and Michael producing a baby with blood type O is zero. Based on their genotypes, their offspring could only possess the genotypes: AB, AO, BB, BO that translates to phenotypes: Blood type AB, A, and B.
