Each symbol is a colony, and the size of the symbol is how many offspring it had, because we were able to use genetic variation to match up parent and offspring colonies, that is, to figure out which colonies were founded by a daughter queen produced by which parent colony.
Fiecare simbol e o colonie, mărimea simbolului reprezintă numărul de urmaşi, pentru că am folosit variaţii genetice ca să determinăm coloniile descendenţilor, adică să ne dăm seama ce colonii provin de la o regină-fiică a unei colonii parentale.
