My best friend is a mirror twin. His brother cried a lot more as a baby. When they became toddlers his brother complained a lot more. Now as adults, his brother still complains and argues a lot more. I don’t understand how they can be genetically identical, have the exact same upbringing, and be so different from the moment of their birth, but they are.
That’s not how identical twins are formed. An egg, fertilized from a single sperm, splits into two, creating two people with identical DNA. You’re thinking of fraternal twins, where two separate eggs are fertilized by two separate sperm.

wait what
Normal: 1 egg + 1 sperm make 1 person
Identical twins: 1 egg + 1 sperm make 2 person
Fraternal (non identical twins): 2 eggs + 2 sperms make 2 person
so i just read the wikipedia article and i don’t udnerstand what it says. i’ll stick with my missconception xD
