Abstract
Study of chromosomes of bivalves is technically difficult. Spermatogonia and spermatocytes, oocytes, and cleavage stages of the fertilized eggs are more favourable than the somatic tissues of the adultss for the study of chromosomes. Hypotonic treatment, prior to fixation, is an essential pretreatment for obtaining well-spread chromosomes. 1he study of the chromosomes of a bivalve, Anadara rhombea, from the Porto Novo waters, has been the first of its kind in an Indian bivalve. Oiakinet'C and first metaphase stages from 'squash' preparations of testis show that in male 2n •= 28 in this species; the sex chromosomes, if any, are not distinguishable.
