✦ Synopsis

The mtDNAs of chicken and Japanese quail can be readily distinguished from each other following electrophoresis after digestion with the restriction endonucleases, Hind 111 and Sal I. In hybrids between female quail and male chicken, the cleavage patterns of mtDNA were the same as the quail restriction fragment patterns. These results indicate that the avian mtDNA is maternally inherited. On the other hand, isozyme analysis revealed that the nuclear encoded enzyme GPI was assembled from both paternal and maternal gene products.
