Why is type O blood more universal?

Answer 1

Yes, we are a rare group. Only 15% of the world's population and dwindling away. Just about every time we breed with a Positive blood type man, we have a Positive blood type child. That means that some day Negative blood will be extinct. O negative blood is the purest blood type on earth. ALSO, no one knows where it originated and isn't connected to anything else on earth.

Answer 2

Type O blood is considered the universal donor because it lacks A and B antigens on its surface. This means it can be transfused to patients with any blood type without causing a reaction. Additionally, type O blood is less likely to cause transfusion reactions as it doesn't have antibodies against A or B antigens.

Answer 3

I actually asked my Biology teacher that very question, and he gave me a very simple yet very complex answer; it has to do with the way people have had children and blended their blood types. Therefore, if people had married different spouses throughout the course of history, we might have different blood types that are common.

Answer 4

Blood can have either A or B molecules that cause the blood to clump if anything but what is contained in the blood is mixed in. Type A can receive both A and O type blood, type B can receive type B and O type blood, and AB can receive A, B, and O type blood, and type O can only receive type O. The reason the blood can accept type O is because it does not have those substances that cause the blood to clump, it is basically a neutral blood type. It is considered "universal" because every single person can receive this type of blood, which is also why it's hard to find because not very many people have straight O blood because it is a recessive type.

Answer 5

O blood group is called universal donors because this group blood can given to any other blood group person.

Answer 6

Because it is. Recessive is essentially where a gene will lose in a conflict, so would normally decline over time.

Another example of a recessive gene is the blue eye gene. If a couple have a child where one parent has bown eyes and the other blue the child is more likely to have blue eyes than brown.

Answer 7

The O allele and Rh positive allele are the most common in the population.

Answer 8

Type O Blood is unique in that it can be used by anyone. If you have Type O blood, you are considered to be a "universal donor". No other blood type is like Type O in this way.
