Seems like they are formed in the womb, like fingerprints.These are identical twins and yet one has symmetrical abs while the other has obvious asymmetry.
>identical twins>not identicalTheir veins also seem to be different patterns, but I can't really get a good look at th same body part on both of them.
>>77306979Veins are interesting, I've read into it. Some appear to have set positions, others are positioned differently depending on the individual. So twins do have different vein distribution, although main ones, so to speak, are positioned similarly."Identical twins" refer to monozygotics. Twins IRL suck, not only are identicals the rare type of twin, they are not perfectly identical like cartoons would have you believe. It's truer to say monozygotic twins are very similar looking people, usually difficult to distinguish at a glance.
