Abstract

Carp species, Cyprinus carpio, from Laguna de Bay was studied. Caudal fin borders were used as the source of chromosome to establish the chromosome number and chromosome classification. The types of chromosomes were designated as class A; double armed mediocentric and submediocentrics, class B; single armed mediocentric, submediocentric and acrocentrics and class C; centromeres on the terminal point. This classification was modified from Ohno (1957). The study revealed that the diploid number of chromosomes of C. carpio was 104 as observed from fifty well-spread c-metaphase cells. Five well-spread c-metaphase cells were studied for classification. Four cells, cell number;, 4, and 5 had more class B chromosomes. All cell owed a greater frequency of class A than class C. Minute chromosomes were also observed. Cell number 1 had 2 pairs (Nos. 39 and 52), cell numbers 2 and 3 had 1 pair each (Nos. 37 and 44 respectively), cell number 4 had 3 pairs (Nos. 37, 38 and 52) and cell number 5 had 4 pairs (Nos. 42-44 and 52 ).
