A variant in the restriction endonuclease cleavage pattern of mitochondrial DNA in the domestic fowl, Gallus gallus domesticus.

The cleavage patterns of mitochondrial DNAs (mtDNAs) were investigated from 15 lines of domestic fowls, Gallus gallus domesticus, using 11 restriction endonucleases. The cleavage patterns with 10 restriction endonucleases were identical in all the lines. A variant was found in a line of White Leghorn in the pattern with MspI digestions. Cleavage patterns of the red jungle fowl, Gallus gallus gallus, were identical to the common patterns shown by the 14 lines of domestic fowls.
