Abstract

Metaphase chromosomes analyzed from the anterior kidneys of Ophieleotris aporos obtained from Lake Taal in Luzon Island, Philippines revealed that the diploid chromosome number was 2n=46. The fundamental number (FN) is 48 (2 submetacentric and 44 acrocentric chromosmes) was known. There was no distinguishable hetemorphic pair of chromosomes in the Giemsa-banded metaphase spreads. This is an initial report on the chromosome set of O. aporos in the this country.

Abstract

The karyomorphology of Glossogobius giuris (Gobiidae) obtained from Lake Taal and some rivers of Cavite in Luzon Island, Philippines was described. Metaphase chromosome analysis (colchicine-sodium citrate-Carnoy's fixation-Giemsa staining procedures) of the hematopoitetic cells in the anterior kidneys revealed that the diploid chromosome number was 2n=46 (46A). Fundamental Number (FN) is also 46, since all chromosomal morphology were acrocentrics without any distinguishable heteromorphic pair of chromosomes in the metaphase spreads from both dry and wet preparations. This study confirms previous reports on the chromosomal sets of G. giuris from India. Keywords : Philippines / Lake Taal / Genetics / Karyomorphology / Glossogobius giuris
