  • species
  • Chromosome painting with DNA probes derived from the flow-sorted macrochromosomes (1-10) of chicken (Gallus gallus, GGA) has been used to identify and distinguish the homoeologous chromosomal segments in three species of parrots, i. e. (kent.ac.uk)
  • The ten GGA macrochromosome paints unequivocally recognize 14 to 16 hybridizing regions delineating the conserved chromosomal segments for the respective chicken macrochromosomes in these representative parrot species. (kent.ac.uk)
  • Among the larger GGA macrochromosomes (1-5), chromosomes 1 and 4 are conserved on two chromosomes in all three species. (kent.ac.uk)
  • In contrast, the smaller GGA macrochromosomes 6, 7 and 8 displayed a complex hybridization pattern: two or three of these macrochromosomes were found to be contiguously arranged on a single chromosome in all three parrot species. (kent.ac.uk)
  • probe
  • The same probe mixture identifies meiotic pachytene, late prophase I, and metaphase I chromosomes. (pnas.org)
  • However, without the precise level of blocking with unlabeled repetitive DNA, the FISH procedure tends to label all chromosomes nonspecifically because of the presence of retrotransposons in the probe. (pnas.org)
  • CytoTest FISH probes are manufactured with genomic DNA obtained either from microdissected human chromosomes or cloned DNA fragments, depending on the probe type. (cambio.co.uk)
  • The results showed signals along their W chromosomes and the use of L. elongatus W probe against L. macrocephalus and L. obtusidens also showed signals over the Z chromosome. (biomedcentral.com)
  • synteny
  • However, the number of synteny association events and identities of microchromosomes involved in such synteny associations remain undefined, due to the lack of paint probes derived from individual chicken microchromosomes. (beds.ac.uk)
  • To delineate the synteny-conserved segments in Accipitridae, a set of painting probes for the griffon vulture, Gyps fulvus (2n = 66) was generated from flow-sorted chromosomes. (beds.ac.uk)
  • fluorescent
  • These probes, coupled with changes in the chromosome-preparation procedure that improve fluorescent signal detection, allowed the development of a FISH karyotyping method that is effective on all tested maize lines. (pnas.org)
  • FORT COLLINS - KromaTiD , a Colorado State University spin-off company, announced it has developed the first fluorescent paint designed to color chromatids. (innovationews.com)
  • The "paint," a mixture of fluorescent DNA molecules tailored to a particular chromosome, is the first specifically designed for chromatids, or one side of a chromosome. (innovationews.com)
  • cladistic
  • Using both a chromosome-based cladistic analysis as well as by mapping of chromosomal differences onto a molecular-based phylogenetic tree, we revealed a number of potential cytogenetic signatures that support the clade of Pandionidae (PHA) + Accipitridae. (beds.ac.uk)
  • mechanisms
  • Sex chromosomes in the genus Leporinus (Teleostei, Anostomidae) present some features that make this group very interesting for the study of sex determination mechanisms and sex chromosome structure, composition and evolution. (biomedcentral.com)
  • phylogenetic
  • We tested the potential of these paints as phylogenetic tools by looking for chromosomal signatures in two lineages of nectarivorous phyllostomids whose independent origins have been statistically supported by molecular phylogenies. (biomedcentral.com)
  • Our results base on chromosome rearrangements suggest the classification following the criterium of tail length may no reflect the real phylogenetic history of Neotropical Psittacidae. (preprints.org)
  • Ideally, detailed investigation of the chromosome architecture of an organism and related groups, placed within a phylogenetic context, is required. (biomedcentral.com)
  • autosomes
  • Nevertheless, the present results did not help to clarify whether Bs were derived from the X chromosome or else from 1 or more autosomes. (karger.com)
  • segments
  • The colors in your Chromosome Painting tell you about your Ancestry Composition, but you can learn even more by looking at the number and length of the DNA segments assigned to each ancestry. (23andme.com)
  • evolution
  • Because of their complexity, the full extent of chromosome evolution in these hominoids is not yet fully documented. (omictools.com)
