Who gets the rights when there's identical twins?

• xyst 7y ago
  The term “identical twins” is a misnomer in terms of DNA. If you have two identical looking people, they will still have unique sets of DNA.

    You are wrong. I'm not talking about "identical looking" people. I'm talking about _monozygotic twins_. They have identical DNA because they're two people spawned from one zygote and therefore have identical DNA.

      Won’t natural mutations give them different DNA after some time?

        Correct: https://www.smithsonianmag.com/smart-news/identical-twins-arent-so-identical-which-makes-twin-studies-harder-119107266/ https://www.smithsonianmag.com/smart-news/identical-twins-ar... And it starts in utero, even at the embryonic stage: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6301568/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6301568/

          The markers in CODIS (law enforcement DNA database) don't cover the whole genome. The markers sold by commercial genetic genealogy databases also don't typically cover the whole genome. The likelihood of the few in utero polymorphisms occurring at one of the covered markers is very low. That means a whole genome would need to be sequenced to determine which twin DNA evidence came from.
