Co-dominance ________________
a)
is a situation in which both alleles are equally strong and both alleles are visible in the hybrid genotype
b)
is a situation in which the dominant allele is stronger than the recessive allele, but both alleles are visible in the hybrid genotype
c)
is a situation in which the recessive alleles are stronger than the dominant allele, within which the recessive alleles are visible in the hybrid genotype
d)
none of the answers are correct.
2.
One of the co-dominant traits studied in class was blood types. If a person has the allele blood type I B i o, what type of blood type does the individual have?
a)
The individual would have blood type A
b)
The individual would have blood type B
c)
The individual would have blood type AB
d)
The individual would have blood type O
3.

a)
The individual would have blood type A
b)
The individual would have blood type B
c)
The individual would have blood type AB
d)
The individual would have blood type O
4.
What is the difference between an antigen and an antibody?
a)
An antigen is part of your bodies defense system, while an antibody is a type of carbohydrate that is attached to RBC's. For example, if a person has blood Type A, the antigen would be A, and the antibody would be B.
b)
An antibody is part of your bodies defense system, while an antigen is a type of carbohydrate that is attached to RBC's. For example, if a person has blood Type A, the antigen would be A, and the antibody would be B.
5.
IF YOU HAVE BLOOD TYPE B, WHAT TYPE OF ANTIGENS, AND ANTIBODIES, WOULD YOU HAVE IN YOUR BLOOD PLASM?
a)
If an individual was blood type B, the antigen would be A, and the antibody would be B. If a person has blood type B, and receives blood type A in a blood transfusion, the A antigens would recognize the foreign blood, and send out antibodies to destroy the foreign blood transfusion.
b)
If an individual was blood type B, the antigen would be B, and the antibody would be A. If a person has blood type B, and receives blood type A in a blood transfusion, the B antigens would recognize the foreign blood, and send out antibodies to destroy the foreign blood transfusion.
6.
If a person had the blood type genotype of I B i o, and another person had the blood type genotype of i o i o, what would the probability that the future offspring would have type B blood? (hint, create a punnet square analysis to determine the probability of blood types found in the future offspring.)
a)
The probability that the future offspring would have type B blood would be 25%
b)
The probability that the future offspring would have type B blood would be 50%
c)
The probability that the future offspring would have type B blood would be 75%
d)
The probability that the future offspring would have type B blood would be 100%
100 %
