Phylogeny of the rock wallabies, Petrogale (Marsupialia: Macropodidae). Part II: Detection of hybridisation among macropodines.

The article discusses research on the phylogenetic relationships of rock-wallabies or Petrogale. It references a study by John A. W. Kirsh at the University of Wisconsin Zoological Museum in Madison, and his colleagues, published in an issue of "Australian Mammalogy." The researchers concluded that distance-generating techniques and single-copy DNA hybridization assume that the entities compared are complex equally. They also found that the failure of natural hybrids to act in ways that are expected of them was affected by the replication phenomenon, sex-chromosome-related difference and maternal effect.
