Monodelphis domestica (gray short-tailed opossum) Gray, short-tailed opossum (laboratory opossum) Lineage: Eukaryota[15557]; Metazoa[7782]; Chordata[3579]; Craniata[3544]; Vertebrata[3544]; Euteleostomi[3500]; Mammalia[873]; Metatheria[172]; Didelphimorphia[3]; Didelphidae[3]; Monodelphis[1]; Monodelphis domestica[1]

Opossums and other marsupial (metatherian) mammals are the closest phylogenetic relatives of placental (eutherian) mammals. Another group of more distantly related mammals, monotremates or prototherian mammals, is comprised of the egg-laying platypus and echidnas. Prototherian, metatherian, and eutherian mammals are more closely related to one another More...than to other vertebrates such as birds, amphibians, or fish. Marsupial genomes are approximately the same size as other mammalian genomes; however, they tend to have fewer, larger chromosomes. The Monodelphis domestica diploid genome is organized in eight pairs of autosomes and two sex chromosomes.Monodelphis domestica is the predominant laboratory-bred research marsupial and has been used to study evolution, development, photo-biology and DNA repair, and neurobiology. It is becoming an increasingly important model organism for comparative genomic research. Less...
