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.
Hvert symbol er en koloni og størrelsen er antal efterkommere den har. Vi kan nemlig bruge genetisk variation til at matche kolonier og deres aflæggere, altså finde hvilke kolonier der er grundlagt af døtre af hvilke moderkolonier.
