meiotic chromosomes and karyotype of puntius ticto (cyprinidae) from kathua region (j &k), india

Somatic karyotype of Puntius ticto (Cprinidae) consists of 2n=50. The karyotype comprises of seven metacentric (m) pair, nine submetacentric (sm) pairs, seven subtelocentric (st), pairs and two pairs of telocentric (t) chromosome and the karyotype formula was derived as 14m + 18sm + 14st + 4t with fundamental arm number (FN) =84. Meiotic stages metaphase I have shown the haploid number exactly half of the diploid chromosome number i.e. n=25. Meiotic stages observed are leptotene, Zygotene, Pacytene and Metaphase I.
