Molecular and classical cytogenetic analyses demonstrate an apomorphic reciprocal chromosomal translocation in Gorilla gorilla

The existence of an apomorphic reciprocal chromosomal translocation
in the gorilla lineage has been asserted or denied by various
cytogeneticists. We employed a new molecular cytogenetic strategy
(chromosomal in situ suppression hybridization) combined with
high-resolution banding, replication sequence analysis, and
fluorochrome staining to demonstrate that a reciprocal
translocation between ancestral chromosomes homologous to human
chromosome 5 and 17 has indeed occurred.
