The so-called ‘golden blood’ has nothing to do with actual gold, but rather has some pretty unique qualities that make people treat it as if it was made of gold. People with this type of blood don’t have any antigens to help the immune system protect them from all kinds of pathogens. But the same antigens also make it harder to receive organic transplants and blood transfusions. Discovered in 1961, this unique blood type can be received by any person on Earth. Yet, there are only 40 people in the world (we know of) that have ‘golden blood’.
Did you know an extra set of genes can turn you into a genetic chimera? There’s nothing to be afraid of as most of the time this condition goes totally unnoticed. But there are also times when it pops out as the visually stunning heterochromia (when a person has eyes of different color) or ‘mosaic skin’. Sometimes this extra set of genes can cause real troubles because your DNA looks different compared to that of your family members. There’s a case when children were almost taken from their mother due to genetic chimerism!
