Supernumerary B Chromosomes of Tetragonisca fiebrigi Share Repeat Content with Standard Chromosome Set of both T. fiebrigi and Tetragonisca angustula (Apidae: Meliponini).

Abstract excerpt

The stingless bees Tetragonisca angustula and Tetragonisca fiebrigi are widely distributed in Brazil, and both are commonly known as "jataí." Our goal was to investigate the possible origin of the B chromosomes in T. fiebrigi, a cytotaxonomic trait that differentiates T. fiebrigi from T. angustula. We analyzed diploid chromosome number (2n), B chromosome incidence, patterns of constitutive heterochromatin, and in...
