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.
Cada símbolo es una colonia y el tamaño del símbolo es cuántas crías tuvo ya que pudimos usar la variación genética para emparejar colonias de progenitores y colonias de crías para entender qué colonias fundó una hija reina y qué colonia de progenitores la produjo a ella.
