Barbie meets Ken …… in TORONTO

11. Februar 2012 Archiv

. . . 26. April 2012 . . . . 18. Biologiewettbewerb der Universität Toronto . . .
. . . Registration Deadline: Friday, March 09, 2012 . . .
 
Barbie and Ken have their first child. Barbie knows her blood type is A, but Ken does not know his blood type. However, Ken knows that both his mother and father have type B blood. Their first child is a boy named Skip. Skip has type O blood. Barbie and Ken do not understand how this happened. Which of the following is the best explanation?

a. Barbie’s genotype is AA, and Ken’s genotype is OO; thus, Skip expresses the O phenotype.
b. Barbie’s genotype is AO, and Ken’s genotype is OO; thus, Skip expresses the O phenotype.
c. Because Ken’s parents are both type B, Ken cannot be Skip’s father.
d. Skip’s blood type will need to be checked after his first month of life if Barbie and Ken want to know his blood type, as it takes about a month for the blood type to develop in a newborn child.
e. Since Barbie has type A blood, there had to be a mix-up in the lab report, as Skip should also have type A blood.
