ah yes, genetic chimeras. Interesting. Do you have strange lines on your skin, perhaps ones that only show up on UV light? There is a type of
chimera where the distribution of the two different 'cell types' (lets call it that for the moment for clarity and brevity) is arranged in a pattern
and reacts to that light. Not glowing, just slightly different than one another and thus can be distinguished.
there are two types of genetic chimeras, one is effectively the a single individual who, early in development, had a seperate and
distinct cell line mixed in with their own cells, and the other is one wherein there was an alteration to the dna of one of one's own cells, but very
early indevelopment, such that all subsequent cells that 'grew' from it were also distinct.
Tho, this 'blood chimera' might be something more specific, and only refer to having, say, two set of the genes that control blood type.
And, atop all that, there are created chimeras, say mice with cow stem cells, or a human with, say, their germ line altered by insertion of an
engineered gene would also be a chimera.
here is an interesting news article on it
and here is a medical dictionary definition
