Remarks
Chromosome mapping with (CA)n, (GA)n and (CGG)n microsatellite probes displayed a similar pattern in both sexes. The (CA)n and (GA)n probes displayed signals in terminal region of almost all chromosomes, whereas (CGG)n motifs found in centromeric region of nearly all chromosomes. Telomeric (TTAGGG)n
