(2008) now report that hybrid sterility between two yeast species is caused by incompatibility between a nuclear-encoded mitochondrial regulatory protein and its mitochondrial-encoded target gene.
متن کاملSpeciation Generates Mosaic Genomes in Kangaroos
The iconic Australasian kangaroos and wallabies represent a successful marsupial radiation. However, the evolutionary relationship within the two genera, Macropus and Wallabia, is controversial: mitochondrial and nuclear genes, and morphological data have produced conflicting scenarios regarding the phylogenetic relationships, which in turn impact the classification and taxonomy.
