Homologous3
  • Banding makes it possible to identify homologous chromosomes and construct chromosomal nomenclatures for many species. (wikipedia.org)
  • Banding of homologous chromosomes allows chromosome segments and rearrangements to be identified. (wikipedia.org)
  • Additionally, the chromosome characters were mapped in a consensus phylogenetic topology previously proposed, revealing a pericentric inversion in the chromosome homologous to GGA4 in a chromosomal signature unique to small New World ground doves. (bvsalud.org)
Chromosomal1
  • Therefore, in comparative cytogenetics, phylogenetic relationships should be determined on the basis of the polarity of chromosomal differences (derived traits). (wikipedia.org)
Probes2
  • Homologies can be identified with high accuracy using molecularly defined DNA probes for fluorescence in situ hybridization (FISH) on chromosomes of different species. (wikipedia.org)
  • Hence, we performed whole chromosome painting (wcp) for paints GGA1-10 and bacterial artificial chromosome (BAC) probes for chromosomes GGA11-28 for Columbina passerina, Columbina talpacoti, Patagioenas cayennensis, Geotrygon violacea and Geotrygon montana. (bvsalud.org)
Karyotypes2
  • During this phase, data on the karyotypes of hundreds of mammalian species (including information on diploid numbers, relative length and morphology of chromosomes, presence of B chromosomes) were described. (wikipedia.org)
  • The banded karyotypes of 850 mammalian species were summarized in the Atlas of Mammalian Chromosomes. (wikipedia.org)
Rearrangements2
  • Comparative chromosome paint and G-banding results suggested that at least one interchromosomal and many intrachromosomal rearrangements had occurred in the diversification of Columbidae species. (bvsalud.org)
  • Our cladistic analysis, considering all the chromosome rearrangements detected, provided strong support for L. verreauxi and P. cayennensis, G. montana and G. violacea, C. passerina and C. talpacoti having sister taxa relationships, as well as for all Columbidae species analyzed herein. (bvsalud.org)
Species2
  • It was found that in most orders, there are species with rates of chromosome evolution that can be considered as 'default' rates. (wikipedia.org)
  • A seemingly logical consequence of descent from common ancestors is that more closely related species should have more chromosomes in common. (wikipedia.org)
