  • chromosomal
  • Single chromosomes or single chromosomal regions were microdissected by laser pressure catapulting and amplified using linker-adaptor PCR. (springer.com)
  • 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)
  • We proposed the corresponding human chromosomal segments for chromosomes of the investigated species and found two syntenic associations shared by G. soricina and A. cultrata . (biomedcentral.com)
  • 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)
  • Our chromosome painting data indicated that the Palearctic common buzzard (BBU) shared several common chromosomal rearrangements with some Old World vultures, and was found to be more closely related to other Accipitridae than to Neotropical buteonine raptors from the karyotypic perspective. (beds.ac.uk)
  • 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)
  • 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)
  • 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)
  • lizards
  • Ezaz T, Sarre SD, O'Meally D, Graves JAM, Georges A (2010) Sex chromosome evolution in lizards: independent origins and rapid transitions. (springer.com)
  • Centromere
  • The relative location of 2 repetitive DNAs, i.e. ribosomal (rDNA) and a tandemly repeated satellite DNA (satDNA), with respect to the centromere, suggested that B chromosomes in the grasshopper Eyprepocnemis plorans derived intraspecifically from the X chromosome. (karger.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)
