Karyotypic description of the stingless bee Melipona quinquefasciata Lepeletier, 1836 (Hymenoptera, Meliponini) with emphasis on the presence of B chromosomes


	Melipona quinquefasciata metaphase with 2n = 18 + 2Bs submitted to C-banding (a), CMA3 (b) and DAPI (c) staining, and to the FISH technique (d). The arrows indicate the rDNA location, while asterisks indicate the B chromosomes and arrowheads indicate an interphase nucleus with two signals. Scale bar: 5 μm.
