title: Assignment of a porcine male-specific DNA repeat to Y-chromosomal heterochromatin.
abstract: Primers were designed to amplify by PCR a 509-bp genomic fragment from male pig DNA, using the porcine male-specific repeat sequence described by McGraw et al. (1988). This PCR product showed male-specific hybridization in Southern blots. Nonradioactive in situ hybridization localized it to the entire length of the heterochromatic portion of Yq. The assignment was confirmed using the PCR primer pDYZ1-S for primed in situ labeling.
