pythagoricus males; they show very similar karyotype and total haploid complement length, with all the chromosomes telocentric.
Usually the chromosomes are telocentric and one of the sex chromosomes is the largest of the complement.
With regard to pair five, Campylorhynchus is submetacentric, whereas Thryothorus and Thryomanes are both telocentric
This in turn gives rise to two stable chromosomes of telocentric appearance.
The techniques for identifying telomere sequences have shown the ephemeral existence of terminal centromeres after breakage and demonstrate that stable chromosomes of telocentric morphology have a telomere at both ends (Werner et al.
In the latter the fission products are invariably of telocentric appearance.
All chromosomes were telocentric and chromosomes were paired by length alone.
lateralis are telocentric, which is rare among bivalves studied so far.
Karyotypes with metacentric chromosomes are generally considered as more pleisomorphic than those with telocentric and subtelocentric chromosomes (Thiriot-Quievreux 1994).
Northwest Pacific abalones only have metacentric and submetacentric chromosomes, whereas northeast Pacific abalones have those types and additionally have intermediates between those types, and two (Minkler 1977) telocentric pairs of chromosomes, or one submetacentric-subtelocentric in this study.
