Abstract: | An analysis was made of the C-banded karyotype of Strophosoma capitatum (Deg.). The results indicate that the chromosome number is 2n = 22 and n Male = 10 + Xyp. The examined karyotype shows a pericentromeric position of constitutive heterochromatin in all autosomes. The shorter arm of the X chromosome is heterochromatic while the y chromosome is wholly euchromatic. Successive stages of spermatogenesis were analysed. |
