Popis: We characterized the chromosomes of the lancelet Branchiostoma belcheri Gray. Testes were removed from adult males, cut up, treated with colchicine (25–50 μg/ml) for 3–6 hr, and dissociated into single cells by pippeting. The dissociated cells were swollen with 5.0–6.5% sodium citrate for 10 min and fixed with methanol-acetic acid (3:1). The fixed cells were dropped onto a glass slide and air-dried. The haploid chromosome number was 18 and diploid number was 36.
