An unusual supernumerary chromosome has been reported for two related avian species,
the zebra and Bengalese finches. This large, germline-restricted chromosome (GRC) is …

We characterize T- and B-lymphocytes from several donors, determining cell diameter, ratio
of nucleus to cell diameter, and refractive index of the nucleus and cytoplasm for each …

The Eurasian common shrew (Sorex araneus L.) is characterized by spectacular chromosomal
variation, both autosomal variation of the Robertsonian type and an XX/XY 1 Y 2 system …

Over the past decade, the free-living flatworm Macrostomum lignano has been successfully
used in many areas of biology, including embryology, stem cells, sexual selection, …

Comparative analysis of micro B and macro B chromosomes of the Korean field mouse
Apodemus peninsulae, collected in populations from Siberia and the Russian Far East, was …

Macrostomum lignano is a free-living flatworm that is emerging as an attractive experimental
animal for research on a broad range of biological questions. One feature setting it apart …

The free-living flatworm Macrostomum lignano is a model organism for evolutionary and
developmental biology studies. Recently, an unusual karyotypic diversity was revealed in this …

Guppy X and Y chromosomes represent an early stage in sex chromosome divergence.
Synapsis and recombination between X and Y chromosomes attract special attention because …

All songbirds studied to date have an additional Germline Restricted Chromosome (GRC),
which is not present in somatic cells. GRCs show a wide variation in genetic content and little …

Abstract Comparison of evolutionarily conserved mammalian chromosomes homologous to
human chromosome 17, performed with microdissected painting probes, revealed …
