Summary:
By comparing genes in the opossum and the platypus, Duke University Medical Center researchers have uncovered evidence that questions the origin of "genomic imprinting" -- a process by which a gene's expression is governed solely by which parent donated the gene copy, rather than by the classic laws of Mendelian genetics, in which genes are either dominant or recessive.

The findings also resolve questions surrounding the structure of the mammalian evolutionary tree and may open the door to better evaluation of carcinogenic agents.
