Abstract
Southern blot analysis of the porcine pituitary glycoprotein common α-subunit gene was performed using porcine genomic DNA from 2 different sources. The BamHI fragments of the common α-subunit gene showed a difference in size between the DNA of Landrace-Yorkshire breed and the other sample purchased from Clontech, whereas the EcoRI-fragments were identical. The results indicate that restriction fragment length polymorphism exists in the porcine common α-subunit gene.
