Abstract

The karyotype of the lungfish, Neoceratodus for steri, is described as 2n = 54, comprising 3 pairs of very large metacentrics, 1 pair of large submetacentrics, 13 pairs of smaller acrocentrics, and 10 pairs of microchromosomes. In addition to centromeric constitutive heterochromatin, C-bands were located on the arms of almost all of the macrochromosomes. The nuclear DNA content of N. forsteri was confirmed as being high (98.6-111.9 pg/nucleus).
