Abstract
The cDNA sequences encoding the adult .alpha.- and .beta.-globin polypeptides of a marsupial, the native cat Dasyurus viverrinus, have been cloned and their nucleotide sequences have been determined. Using these cDNA clones we have determined the chromosomal location of the native cat .alpha.- and .beta.-globin genes by in situ hybridization to fixed metaphase chromosomes and by hybridization to DNA extracted from chromosomes purified by a fluorescence-activated cell sorter. Using two independent methods of gene assignment we have shown the .alpha.- and .beta.-globin-like gene sequences to be asyntenic in the native cat, the .alpha.-globin-like sequences being on chromosome 2 and the .beta.-globin-like sequences being on chromosome 4.
