G-banding patterns of the chromosomes of tonguefish<i>Cynoglossus semilaevis</i>Günther, 1873

Abstract

This paper reports the G-band patterns of the metaphase chromosomes of tonguefish Cynoglossus semilaevis Günther, 1873, the first description and numbering of the karyotyped bands in metaphase chromosomes. The G-banding method stained positively 68.1% of the chromosome surface in C. semilaevis; a total of 171 G-bands (89 positive, 74 negative and eight variables) were recorded in 20 pairs of autosomes and in one pair of the sex-chromosomes Z and W.
