Is there any difference or differences between the blood of a white man and a black man?

Question

especially between Americans, europeans and Africans

Answer 1

The only difference between the two are the color of thier skin. I have received blood from an African American and it didn't make me sick or anything ;p

Seriously, as long as the blood type and RH factor are the same (+-), there is no difference.

Answer 2

Worldwide Blood Type Stats:

O=46%

A=39%

B=11%

AB=4%

RH Factor:

Positive (+)=85%

Negative (-)=15%

Note: Virtually all RH (-) blood belongs to Caucasians.

Neither Skin color nor Ethnicity makes a different species.

Answer 3

nothing

Answer 4

None whatsoever.  Its all exactly the same.

Answer 5

Nope =]

Answer 6

No, the difference is in their genes. Well I am not sure about the blood, I wasnt aware of any differences.

Its interesting how the races became what they are, I suggest you look it up and read, its very interesting and worth reading.

Answer 7

No, even if there is a prevalence of  some Rhesus factors in some ethnic groups  (a little bit less occurrence of A and an higher occurrence of B in some African ethnic populations, but more or less the same occurrence of O . Much less  negative than positive).

Dr .: your reference about sickle cell disease (Sickle, not cycle) is  not based on scientific data .

Sickle cell disease is diffused in Africa, China, South Europe, Arabic countries, India  across all ethnic groups. HJust is more present in areas traditionally malaria stricken. Seems in fact that it is a mutation linked to a trial to protect from malaria gone wrong.

Ever heard about Price's equation linking Malaria and sickle cells disease?

The Price equation is a simplified mathematical model of the genetic evolution of sickle-cell anaemia.

The malaria parasite has a complex life cycle and spends part of it in red blood cells. In a carrier, the presence of the malaria parasite causes the red blood cell to rupture, making the plasmodium unable to reproduce. Further, the polymerization of Hb affects the ability of the parasite to digest Hb in the first place. Therefore, in areas where malaria is a problem, people's chances of survival actually increase if they carry sickle-cell trait (selection for the heterozygote).

In the USA, where there is no endemic malaria, the prevalence of sickle-cell anaemia amongst African Americans is lower (about 0.25%) than in West Africa (about 4.0%) and is falling. Without endemic malaria from Africa, the condition is purely disadvantageous, and will tend to be bred out of the affected population.

Duffy antigen is ANOTHER genetic mutation related to malaria reaction and present in different ethnic groups

Answer 8

When typing blood it goes by A, B, 0 and variations of that.

Then it is divided by male or female, because of hormones.

But color has nothing to do with the blood.

The only difference between the two or that in the 3rd layer of skin.

Which has 7 layers one has more melanin.

Answer 9

matilda is correct. there is also a difference on the cellular level that is still being worked on. when that is determined we will probably be able to cure (not treat) cycle cell anemia.  

Answer 10

No and each can be used the save the other.

Answer 11

Yes, I would assume so based on the fact that certain races are more prone to certain illnesses.

Answer 12

Blacks tend to have a higher incidence of sickle cell anemia, but otherwise there are no differences that I am aware of.  Both can donate blood to each other, so long as their blood types are compatible.

Answer 13

no difference at all.

it's all red and can saves peoples lives.

Answer 14

Yes. Virtually all Africans are negative for the duffy blood protein factor, making them 'Duffy negative' (d-), and making interracial blood transfusions a bit risky if a Eurasian donates to an African. Also, it unfortunatekly makes them more susceptible to HIV.

Also, Europeans are the only people to commonly be rhesus negative, It's seen in less than a tenth of a percent  of the population in Africa and Asia.
