FIGURE 7. Triatoma bahiensis (2n= 22 chromosomes), male meiosis, C-banding. (A) Early first meiotic prophase: several heterochromatic chromocenters spread in the nucleus (arrowheads). A large chromocenter consists of the association of sex chromosomes plus autosomal bivalents (arrow). (B) Diplotene stage: the association between two autosomal bivalents (arrowheads) with associated sex chromosomes (arrow) is observed. (C) Diakinesis or later diplotene: ten bivalents and both sex chromosomes (XY) are clearly identified. The Y chromosome is entirely C-heterochromatic (arrow) and the X chromosome is euchromatic.
