Identification of honeybee subspecies. a Bar plot result of the InStruct assignment test for K=2 under
the admixture model. Colours indicate the relative contribution of each of the two subspecies (A. mellifera
mellifera, gray; A. mellifera mellifera, white) recovered from the data for each individual (column) in each
colony (delineated with black vertical lines). b–e Distribution of assignment indices based on microsatellites (b,
d) and wing morphometrics (c, e). The graphs b and c correspond to indices at the level of workers and graphs
d and e correspond to indices at the level of colonies. In all graphs higher values of the indices mean more
similar to A. m. carnica and smaller values mean more similar to A. m. mellifera.
