Chromosome number in ten species of the genus Tisbe (Copepoda: Harpacticoida)

  • I. Lazzaretto-Colombera
Article

Abstract

Of 10 species of the genus Tisbe, 9 were shown to possess the same haploid number of 12, whereas only 1 has a haploid number of 8. The hypothesis is advanced that n=12 is the primitive condition in the genus Tisbe and that T. biminiensis with n=8, is a recent form.
