Select the QUESTION that corresponds to the displayed ANSWER.
incorrect
11. C --> In most cases these alleles are totally responsible for determining blood type phenotypes. The inheritance usually follows simple Mendelian patterns. However, there are rare exceptions such as the Bombay Phenotype described in the tutorial.




incorrect
12. A --> They are relatively large protein molecules that identify a blood type. Each antigen type has unique traits that, in a sense, make it like a lock that only a specific antibody key can fit.




incorrect
13. A --> Europeans have the highest frequency of Rh negative people (40%), which puts them at the highest risk for this problem. About 13% of newborn Europeans are at risk, but we can now prevent the life threatening complications in most cases.




incorrect
14. A,B,C --> Look at the other answers to see further explanations.




incorrect
15. A --> If they produced anti-A antibodies, it would destroy their own blood. However, they do normally produce anti-B antibodies since B type blood would be alien to them.




incorrect
16. B --> Erythrocyte literally means red cell in Greek.




incorrect
17. A --> Because of the Bombay Phenotype and other possible exceptions, the ABO blood type system is not conclusive in determining whether or not someone could be a parent of a particular child. The other two kinds of evidence are much more reliable.




incorrect
18. C --> The liquid component of blood that we call plasma is the most abundant substance in blood. However, red cells are a close second.




incorrect
19. A,B & C --> Look at the other answers to see explanations.




incorrect
20. C --> The rules of dominance for the ABO system are that A and B are both dominant over O (i.e., O is recessive) and A and B are codominant.
