Then Dracula Said, You're Not My Type!
Blood types are classifications of blood according to "the presence or absence of inherited antigenic substances on the surface of red blood cells." The majority of these antigens are proteins, carbohydrates, glycoproteins, or glycolipids. Finally, a person inherits their blood type from both parents.
In the United States, the percentage break-down of the different types is as follows:
Question 1: What blood type are you?
- O+ 37.4%
- A+ 35.7%
- B+ 8.5%
- AB+ 3.4%
- O- 6.6%
- A- 6.3%
- B- 1.5%
- AB- 0.6%
Question 2: Are the above eight blood types the only ones possible (i.e. the percentages add to 100%)? Investigate and explain.
Question 3: The above data is for the United States. Is the break down the same for other countries/cultures as well? Investigate and explain.
Question 4: If you were type A, where would you want to live (if access to blood type was your primary criteria)? How about if you were Type A? Type O?
