The Anunnaki may have reptilian blood too, as they intermixed with their creations.
We don’t specifically know how our DNA was manipulated. What we DO know is that only 20 of the 64 codons in our DNA are active.
Additionally, our human DNA differs dramatically from all other primates as we only have 46 chromosomes compared to 48 in other primates. The first two chromosomes appear to be fused together, which may explain part of the genetic manipulation by the Anunnaki.
In the following video, Sean David Morton talks about our chromosomes, reptilians and other galactic races:
According to Dee Finney:
The Reptilians are tracking those with Rh-Negative Factor Blood. Going back into time…. the Rh-Neg Hybrids came from the Draco Caverns in the Carpathian Mountains. They were mostly red Haired, with Green Eyes and Black haired, with Brown Eyes. They tried to infiltrate themselves into the Blond/Brown Haired, with Blue Eyes, Civilization…. Rh-Negs are Hybrids. They are Part Reptilian/part human. If two Rh-Negs try to have a baby it will usually die or be born a “Blue Baby”, because it is not processing oxygen properly. Thus “Blue-Bloods”, if they survive. 5% of the Earth’s population are currently Rh-Negatives. But, they are 15% of the population of the England and the USA.
