The chromosomes in the maturation of the germ cells of two species of triclad Turbellarians.

Abstract / Notes

[reference from Sluys R 1989 (citation)]

Maturation of the germ cells of the 2 hermaphroditic spp., Curtisia foremanii and Bdelloura candida, were
studied. In both spp. n = 6, 2n=12. A tendency of the chromatids comprising individual chromosomes to
separate from one another at certain times was noted in both spp.; this results in giving the appearance of
a
larger no. of chromosomes than the germ cells actually possess. A further source of apparent increase in
chromosome number in Curtisia oocytes is the presence of some deeply staining, non-chromatin material. No
significant differences in number, form and behavior of chromosomes of [male] and [female] complexes were
noted, with the possible exception of the tendency of the chromatids to separate from one another, to be
greater in the [female] than in [male] germ cells.
