Abstract

We present a technique (W-CGH) based on Comparative Genomic Hybridization (CGH), but using whole DNA probes, which permits the identification of chromosomal polymorphisms related to highly repetitive DNA sequences that exist between the two genomes compared. The procedure employs two differently colored whole DNA probes from two different individuals that are mixed and hybridized to metaphase chromosomes. The method provides a simple way to map whole genome differences for highly repetitive DNA sequences between two individuals, since it does not require chromosome-specific probes.
