CHROMOSOMES OF THE PHILLIPINE SNAKE-HEAD GUDGEON, OPHIELEOTRIS APOROS (ELEOTRIDAE) FROM LAKE TAAL, LUZ ON ISLAND.

Abstrak

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.
