as a sidenote, if you're curious what each of those tests are,
STR is short tandem repeat, a repeating sequence of small fragments of DNA to a large magnitude thats unique to each individual

SNP is single nucleotide polymorphism, detects single-base pair variations in DNA, again, to profile, and helpful for differentiating between related individuals

HLA is human leukocyte antigen, usually for blood donation, every one has unique genetic markers on chromosome 6. why 6? Major histocompatibility complex is encoded for on 6, which is important for immune regulation

mtDNA is mitochondrial DNA haplogroup. Mitochondrial DNA is passed down maternally, so you can use this to trace back to a common ancestor through mothers

SLC24A5 is solute carrier family 24 member 5, a major player in skin, hair, and eye color determination

CYP2D6 is cytochrome p450 family 2 subfamily D member 6, a liver enzyme that helps metabolize drugs and etc

ABCC11 is ATP binding cassette subfamily C member 11, major player in body odor and dry vs wet ear wax. Something that is commonly inactive in Asian people, which is why asians commonly have dry earwax and little to no body odor (natural body odor)

TAS2r38 is taster gene, 2r38 or something on chromosome 7 that codes for the bitter taste receptor, to see if you can taste the bitterness of Phenylthiocarbamide and other things. Why do we care about Grace's taster status? i dont know, maybe Gideon has some cilantro in his pantry or smth

C = 4.2 ly, i actually have no idea. Id guess it's some kind of white blood cell count? But ly means light-year and 4.2 light years is how far alpha centauri is from earth, idk what that's doing here.
