twins? hell, you’ll see different sequences between individual cells in the same person.

- zinekeller 6y agoYes, it indeed happens on a non-chimeric person (just try comparing the DNA from a muscle in arms versus legs, or even head hair and genital hair). I don't know the point of the study (except if it is just to undeniably confirm this scientifically because some doctors still don't believe that identical twins are not quite identical).
- zxcb1 6y agoAnd then there is the microbiome ...
- irrational 6y agoWould the microbiome be similar growing up (assuming both are living and eating the same foods in the same places/family) and then diverge later when they go their separate ways?
- zxcb1 6y agoFrom what I understand, it is a continuous exchange with our environment, the same way we catch a disease.
- hobofan 6y agoI would assume that the point of the study is to also quantify the amount of mutations so that future twin-based studies can more accurately attribute differences that also exist between twin pairs.
- rootusrootus 6y agoThat's interesting. I wonder what the typical variation is within a single body, versus between monozygotic twins.
- leemailll 6y agoWell, I can give one well-known example for this in genetics. Females carry two X-chromosome, against male's X and Y. There is one thing called X-inactivation, which means one of the X chromosome in the cell is inactivated randomly in cells. By this, even organs only carried the same kind of cells are mosaic in aspect to genes in X chromosome. Then think about a well-know X-chromosome linked disease, the Rett Syndrome, and the cell in body, in the brain.
