Seven genes on the short arm of human chromosome 3 map to two regions on Macropus eugenii (tammar wallaby) chromosome 2.
Seven genes were mapped by in situ hybridization to metaphase chromosomes of the marsupial species Macropus eugenii, using a series of human-derived cloned probes (six cosmids and one cDNA). The genes were located in two widely separated clusters on the long arm of M. eugenii chromosome 2, in contrast to their location in a single cluster on the distal half of the short arm of human chromosome 3. Multiple rearrangements had to be involved in the evolutionary divergence of these chromosome segments from the unknown arrangement in the common ancestor.
