A Comparative Study of G-banded Karyotypes in Eight Species of Owls.

Abstract

G-banded partial karyotypes were compared among eight species of owls from six genera, in order to supplement our previous report (Rebholz et al. 1993). A general feature of highly conservative nature of banding pattern homology was recognized in the eight species here concerned, without evidence of intra-arm inversions or deletions, but with some derivations from the putative ancestral karyotype involving two Robertsonian translocations, three pericentric inversions and some additional sub- or paracentromeric G-bands.
