Fire ants hide a chromosome surprise: polyploid cells revealed in invasive species

Fire ants, one of the world's most notorious invasive species, have been found to carry polyploid cells — cells containing extra full sets of chromosomes — a surprising genetic trait for an insect. The discovery sheds new light on the biology that may help fire ants adapt and thrive in new environments, and is drawing attention from biologists interested in chromosome evolution and invasive-species genetics.

Why now: New research revealing unexpected polyploid cells in fire ants is a striking finding for genetics and invasive-species biology.
