Mammalian centromere function depends upon a specialized chromatin organization where
distinct domains of CENP-A and dimethyl K4 histone H3, forming centric chromatin, are …

Spermatogenesis is a complex sequential process that converts mitotically dividing
spermatogonia stem cells into differentiated haploid spermatozoa. Not surprisingly, this …

The spermatozoon is considered by many to be a silent vessel whose only function is to
safely deliver the paternal genome to the maternal oocyte. As a result, the paternal …

Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of
their position is a powerful way to monitor genome organization in different cell types and …

We have used a combined approach of phylogenetics and cytogenetics to describe
karyotype evolution in Diprotodontia. Molecular relationships of diprotodontian marsupials …

BACKGROUND Many genetic defects with a chromosomal basis affect male reproduction
via a range of different mechanisms. Chromosome position is a well-known marker of …

We used chromosome painting to show directly that chromosomes occupy fixed positions in
the nuclei of mammal but not chicken sperm. We found that the positions of homologous …

Chromosome sorting by flow cytometry is the main source of chromosome-specific DNA for
the production of painting probes. These probes have been used for cross-species in situ …

Recently it has been shown that the nucleus of the human spermatozoon appears to
possess a specific architecture. The current prevailing view is that spatial organization of the …

The first specimen of platypus (Ornithorhynchus anatinus) that reached Britain in the late
18th century was regarded a scientific hoax. Over decades the anatomical characteristics of …
