Abstract

Abstract
To identify the species, understanding the characteristics of the species, explore the possibility of speciation, mutations in the study population, and many other purposes. In this method for studying colchesin bath, karyotype use for immature worms. After reviewing the slide karyotype of polychaeta (Nereis sp.) and observation and analysis of  50  plaque metaphase plate chromosome number of the species found 2n=28 from all set chromosome, 14 pairs of chromosome detected 3 pairs metacentric , 9 pairs from sub metacentric and 2 pairs from telocentric. Since the samples were immature (in seasonal samples weren’t found any adult worm). The sex chromosome are not visible discernable.
