Identification of a near-telomeric marker for the long arm of LG chromosome 4. A large portion of the q arm of LG chromosome 4 consists of a heterochromatic region, which made finding a near-telomeric marker probe difficult for this chromosome arm. zC079A18 (labeled in orange) was established as a near-telomeric marker probe for the q arm of LG chromosome 4 (denoted by orange arrows). Also shown is the near-centromeric marker for LG chromosome 4, zC091G03, (labeled in white, denoted by white arrows) and BAC clone zC207E19, which localizes to the heterochromatic region of the long arm of LG chromosome 4 (labeled in green, denoted by green arrows).
