[Homology of G-banded mammalian chromosomes].
Linkage relationships of homologous loci and high resolution G-banding patterns of man, mouse, rat, chinese hamster, rabbit, cat, mink, pig, ox and sheep were used for identification of 11 evolutionary conservative autosomal regions. The distributions and inversions of these regions in the ancestor genomes of some phylums have been shown. For example, the regions homologous to human Ip region were detected in cat, mink and rabbit genomes. In the genomes of rodents studied the intraregion inversion was detected. In the ox and sheep genomes the distal end deletions were detected within these regions. In the pig genome these regions were represented solely by disruptions. We supposed that the rapid "catastrophic" chromosomal evolution took place during short time periods of some orders and families separation.
