Abstract
Bright-field microscopy of silver-stained pachytene spermatocytes of a male Indian muntjac, Muntiacus muntjak revealed that (a) the synapsis between the autosomal homologs, including the long arm of the X and Y2, was normal, (b) the nucleolus organizer regions were present in both the No. 1 bivalent and the long arm of the X and Y2, (c) the accessory structures of the X chromosome short arm in the forms of light and dark thickenings and the hairpin-like bend were present despite the X-autosome translocation, (d) a short synaptonemal complex was present between the Y1 (real Y) and the short arm of the X chromosome, and (e) the centromeric orientation of the Y1 and Y2 chromosomes was in Cis configuration as opposed to the X chromosome.
