Ensembl .This release of Ornithorhynchus anatinus data is assembled into supercontigs, so there are no chromosomes available to browse.
A few example data points :
The genetics,
physiology and biochemistry of platypus have received relatively little
attention considering the evolutionary relationship between platypus
(and echidnas) and eutherian and marsupial mammals. The platypus genome
is particularly remarkable, being divided up into large and small chromosomes
reminiscent of the macro- and microchromosomes of reptiles and birds.
The platypus has ten sex chromosomes (5X, 5Y) that form a chain at male
meiosis that links mammal and bird sex determination. However with the
absence of the mammalian sex-determining gene SRY sex determination is
still a mystery in platypus.
The sequencing was carried out by Washington University Genome Sequencing Center. The platypus genome of an animal nicknamed "Glennie" (collected at the Upper Barnard River on Glen Rock Station, New South Wales) was sequenced to a total of 6x whole genome coverage. The sequencing strategy combined whole genome shotgun plasmid, fosmid and BAC end sequences. While production sequencing is nearing completion, a BAC-based fingerprint map will be developed with a target of 12x clone coverage. Funding for the sequence characterization of the platypus genome is being provided by the National Human Genome Research Institute (NHGRI), National Institutes of Health (NIH).
