    "Blue blood" is an English idiomatic phrase for "noble birth." The term is an English borrowing of the Spanish phrase, sangre azul, ("blue blood"). Spanish nobility used sangre azul to differentiate between classes of nobility descended from the Moors and those descended from the Visigoths.

    'Blue blood' is a literal translation of the Spanish 'sangre azul'. ... The expression probably originated in the blueness of the veins of people of fair complexion as compared with those of dark skin.

    "Blue blood" was answer to individuals mostly in Europe whose blood never died inside or being with contact with their tissue. Other called them "blue blood" because of their tissue and skin had been blue as result and blue part of blood separated formed into blue tissue with additional chemistry from birth - or knowledge.

    Almost all had been hunted to be killed, and with their hearts not working, their blood and tissues had been still living with hundreds years buried in grounder.

    They had been last from the hunted village where all had been living 20.000 years, minimum years with not more than 2000 or 20,000 residents, maybe I am in error with one of the zeroes.

    Consensuses about other things, made some individuals to decide on their own to go to hunt them, they had been ordinary farmers or fisher-mans or plants farmers.

    Last alive, after put 2000 years ago protected to hibernate from his friends in liquids and crystals, for leaving genetic prove, had been collected (some say stolen) from Russians for research (maybe will finish in some bunch hole used for elements Idk).

    They while alive, had been the race that had been transferring the knowledge from the other planets, maybe the last of their kind - they had been descendants of less mixed "royal" race (working).

    All "true blue royal bloods" had been hunted until extinction from European individuals through history of Europe. Europeans are cursed, I live in Europe too but I'll have to check dna if I am european or not.

    In the past some Europeans had been hunting the cyclops and their civilization until their extinction, too, they had been "blue blood too" last remains as prove I saw been removed without trace ~10 years ago, separated head with very sharp "roman sword".

    Europeans kill everyone that will not kill them or will have ignorance for normal life, for having - simply, leeches.

    It simple, ... insects are lower class blood "mortal" and they attack humans.

    Real humans are dead, animals with weak and mortal bloods hunted them.

    There are few mixed race, from them and the animals. I hope they will save themselves from mortal animals.

    Do some people really have nobility in their DNA?

    no, it doesn't work that way. Everybody is related. Everybody (with a normal genome) has 23 chromosomes from either parent, and passes on 23 of their own to a child they make - there's no calculating or predicting which ones

    Despite what quora says, the term "blueblood" originated in Spain. The rich never had to work in the sun and had little pigment (melanin) in their skin to cover their veins, which appeared blue. The blood itself varies from scarlet (fully oxygenated) to crimson, (lacking oxygen).

    If by "blue blood" you mean royal blood, then yes.  You can determine by DNA if someone is a relative of Queen Elizabeth, for example.  Since she is royal, by extension, her blood is also royal, so based on that, those who are her blood relatives, those who have her DNA, have royal blood, too, are "blue bloods."

    Now, is there a "king" gene? No.  Obviously not.  But we can tell by blood, by DNA testing, whether or not someone is royal by comparing their blood to the blood of someone else who is royal.  If the DNA matches that royal's blood to such extent that we can determine with near 100% certainty they are a blood relative, then we know that they have royal blood, even if whatever royalty don't recognize it or confer any royal title on the person having that so-called "blue blood."

    The term came about in reference to the Rh negative blood in the European royal family.  Since they were largely inbred, there is a higher rate of Rh negative blood among European royals than in the general population.  Their blood isn't really blue, it was just a characteristic that was emphasized to indicate what royalty "should" be.

    Everybody’s blood is the same color. And many of us that can trace our family history back far enough may find some “nobility”.  But what is nobility??  A ruling class, those who were lucky enough to be put in power??
