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.
