Medical science and ethnic disparities in bone marrow donor registry lists have once again illustrated the reality of race as a biological concept, disproving leftist lies which claim it is a “social construct.”

New reports which have focussed on the problems surrounding suitable matches for bone marrow transplant patients have inadvertently revealed why race does exist, and why it matters for humanity’s sake.

The statistics revealed that:

- White British people have a 1 in 3 likelihood of finding a bone marrow transplant match.

- Asian or black people living in Britain have a 1 in 125,000 likelihood of finding a bone marrow transplant match.

- People of mixed race living in Britain have a 1 in 200,000 or more likelihood of finding a bone marrow transplant match.

- There are 16.9 million people on the NHS Organ Donor Register. Of this number only 1.2 percent are Asian and 0.4 percent are black.

- There are 7,800 patients currently waiting for a transplant, of whom 1,521 (19.5 percent) are Asian and 779 (9.98 percent) are black.

The statistics are significant because they reveal that race is a major factor in determining biological diversity and those different racial groups have different attitudes towards social responsibility projects such as organ donation.

Transplanted organs require the same blood and tissue type in order to prevent rejection by the body’s immune system.

However, compared to organ transplants, bone marrow donations need to be even more genetically similar to their recipients.

Since all the immune system's cells come from bone marrow, a transplant actually introduces a new immune system to a person. Without genetic similarity between the donor and the patient, the new white blood cells will attack the host body.

In an organ transplant, the body can reject the organ, but with marrow, the new immune system can reject the whole body.

According to the World Donor Marrow Association (WDMA), the chances of white people finding a match within their racial group is two out of three, while other racial groups have a one in four chance.

The WDMA holds a global registry of donors, which is still disproportionately represented by white people from the US, UK and Germany.

The chances of a person of mixed racial origin finding a match is even less because of the complex genetic issues involved. People inherit blocks of tissue type from both parents, which means that mixed-race children have tissue types which are the rarest of all.

Usually, only people of identical racial origin even have a hope of finding a matching donor.

This means that people of mixed racial origin in need of major organ transplants have almost no chance of finding an exact match, even in highly mixed societies in which the gene pool is very intertwined.
