“…GTG-banding was applied in 1973 to analyze the fine structure of gorilla chromosomes and to identify homologies with chimpanzee and human chromosomes Lejeune et al, 1973). Chromosome heteromorphisms of repetitive sequences in the gorilla genome have been studied by several groups (e.g., Miller et al, 1974;Schmid et al, 1986;Haaf and Schmid, 1987;Marks, 1993). Furthermore, fluorescence in situ hybridization (FISH) with human probes has been performed on gorilla chromosomes using alphoid sequences (Baldini et al, 1993;Archidiacono et al, 1995), gene-specific probes (Matera and Marks, 1993;Ried et al, 1993;Nickerson and Nelson, 1998;Tanabe, 1999), subtelomere-specific probes (Kingsley et al, 1997;Conte et al, 1999), the chromosome arm 2q-specific probe (Wienberg et al, 1994), whole-chromosome painting probes Stanyon et al, 1992), and the chromosome bar code technique (Müller et al, 1997;Wienberg and Stanyon, 1997).…”
