Silver-negative NORs in Pamphagus ortolaniae (Orthoptera: Pamphagidae)
European Journal of Entomology, 2008 The present paper reports some cytogenetic peculiarities observed in the Ag-NORs of Pamphagus ortolaniae chromosomes, the unusual behaviour of ribosomal sites after silver staining and the intense Ag-positive reaction of centromeric regions at ...

A family case of fertile human 45,X,psu dic(15;Y) males [PDF]
, 2006 We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

Identification of white clover (Trifolium repens L.) cultivars using molecular markers
Plant, Soil and Environment, 2004 The different molecular analysis for specification of white clover (Trifolium repens L.) populations was studied between 2002 and 2003. RAPD, SSR (microsatellites), rDNA and PCR-RFLP markers were used for this study.
