Full Idea

It is suggested that conception cannot be the boundary for the beginning of a genetic person, because monozygotic twins can split at any time during the first two weeks.

Gist of Idea

Conception isn't the fixed boundary for a person's beginning, because twins are possible within two weeks

A Reaction

Interesting, but not convincing. If I suddenly learned that I could fission into twins tomorrow, I would be no less of a single person today.
