This report summarizes a decade of morphological and molecular research on the
phylogenetic relationships of didelphid marsupials (opossums), a substantially intact …

In order to test the results of a previous study of didelphid marsupial phylogeny based on
IRBP nuclear gene sequences (Jansa and Voss, 2000. Phylogenetic studies on didelphid …

Chromosomal data have been underutilized in phylogenetic investigations despite the
obvious potential that cytogenetic studies have to reveal both structural and functional …

Among the advanced karyotype analysis approaches embraced by animal cytogenetics
during the past decade, chromosome painting has had the greatest impact. Generation of …

Marsupial and monotreme mammals fill an important gap in vertebrate phylogeny between
reptile-mammal divergence 310 million years ago (mya) and the eutherian (placental) …

The 320-kb human pseudoautosomal region 2 (PAR2) at the tips of the long arms of the X
and Y chromosomes is thought to have been duplicated onto the Y chromosome recently in …

Karyotypes of 127 individuals, representing 19 species of 10 genera of Brazilian marsupials
(Didelphidae) were determined, with karyotypes of Gracilinanus emiliae and G. microtarsus …

Marsupials are “alternative mammals” that differ from eutherians most spectacularly in their
mode of reproduction and sexual differentiation. They represent a 160-million-year-old …

The newly sequenced genome of Monodelphis domestica not only provides the out-group
necessary to better understand our own eutherian lineage, but it enables insights into the …

Decades before the recent advances in molecular biology and the knowledge of the
complete nucleotide sequence of several genomes, cytogenetic analysis provided the first …
