Abstract
The testes of golden snails Pomacea canaliculata (D' Orb) collected from Pili Drive, U.P. College, Los Banos were fixed in freshly prepared Carnoy's solution and macerated in 2% lacto-aceto-orcein. Permanent mounts of spermatogenetic cells were prepared and examined under the light microscope. Meiotic index was determined. Results of meiotic index suggest that insemination potential was relatively high (59.9%). Four types of Interphase nuclei forms were observed with different sizes. Chromosome count ranged from 6 to 15 with a mode of n = 12. Pachytene chromosomes were the most frequent stage observed while Telophase I was the least observed. Average lengths of pachytene chromosomes ranged from 0.112 to 0.059 . Meiotic divisions were normal. Qualitative analyses were done on interphase and meiotic stages.
