Of course they are....we're all human! The human nucleotide bases are adenine (A), cytosine (C), guanine (G) and thymine (T). It's not the base pairs responsible for distinct populations, however, but the sequence of the base pairs.


I'm certain that the 99.9% figure comes from base sequences. If it was just a question of the nucleotide bases themselves, the figure would be 100%, since all life on earth use the same 4 nucleotides in their DNA. (Actually, I think that some viruses have DNA with Uracil replacing Thymine, if I recall correctly.)
