Answer the following before beginning the case study. What are the four human blood types? _____, ______, ______, _______ What are the three alleles that determine the blood types? ____, _____, _______ What is the genotype of a type O Individual? _________ What are the possible genotypes for a type A individual? ______ and _______ What is the allele interaction between the type O allele and type A allele? _____ What is the allele interaction between the type O allele and Type B allele?_______ What is the allele interaction between the type A allele and type B allele? ______ Could a person who has type A blood, be a parent of a type O child? Explain. Could a person who has type AB blood be a parent of type O child? Explain. Could a person with type B blood be a parent to a type A child? Explain. A second of human blood type is the Rh 0 factor. The presence of Rh D (Rh +) is dominant to the absence of the RHD (Rh-) What are the potential genotypes of an individual who is Rh+______and_______ A person with a negative Rh D factor a has a genotype of_______ Could a person that is Rh+ be a parent to a child that is Rh-? Explain. What do you think is going on with these two families? The hospital would have simple things like Diana\'s blood type on file. How could you use blood type to figure out what is going on? Solution A, B, AB and O IA and IB and the i allele i allele IAIA or IAi IA is dominant over i IB is dominant over i IA and IB alleles are co-dominant Yes, A blood group person with heterozygous genotype when married to A, B or O person can get a baby with O blood group. Example IAi x IAi = IAIA (A type), IAi (A type) , ii (O type) No, Because AB person gives IA and IB alleles which results in a baby which is either A, B or AB type.

1. Answer the following before beginning the case study. What are the four human blood types?
_____, ______, ______, _______ What are the three alleles that determine the blood types?
____, _____, _______ What is the genotype of a type O Individual? _________ What are the
possible genotypes for a type A individual? ______ and _______ What is the allele interaction
between the type O allele and type A allele? _____ What is the allele interaction between the
type O allele and Type B allele?_______ What is the allele interaction between the type A allele
and type B allele? ______ Could a person who has type A blood, be a parent of a type O child?
Explain. Could a person who has type AB blood be a parent of type O child? Explain. Could a
person with type B blood be a parent to a type A child? Explain. A second of human blood type
is the Rh 0 factor. The presence of Rh D (Rh +) is dominant to the absence of the RHD (Rh-)
What are the potential genotypes of an individual who is Rh+______and_______ A person with
a negative Rh D factor a has a genotype of_______ Could a person that is Rh+ be a parent to a
child that is Rh-? Explain. What do you think is going on with these two families? The hospital
would have simple things like Diana's blood type on file. How could you use blood type to
figure out what is going on?
Solution
A, B, AB and O
IA and IB and the i allele
i allele
IAIA or IAi
IA is dominant over i
IB is dominant over i
IA and IB alleles are co-dominant
Yes, A blood group person with heterozygous genotype when married to A, B or O person can
get a baby with O blood group. Example IAi x IAi = IAIA (A type), IAi (A type) , ii (O type)
No, Because AB person gives IA and IB alleles which results in a baby which is either A, B or
AB type
