Knowledge graph centered on Comparative chromosome painting (Brassicaceae) with 23 nodes and 49 connections. Top connected: Young inversion with multiple linked QTLs under se, local adaptation, ecological speciation, quantitative genetics, cytotype variation.

Description

Chromosome-specific BAC contigs of Arabidopsis thaliana were used as painting probes to analyze mitotic and meiotic chromosomes of C. cordifolia. Fluorescent signals were detected and analyzed to determine chromosome structure and evolutionary relationships.

Typical Equipment

  • RNase
  • pepsin
  • biotin-dUTP
  • digoxigenin-dUTP
  • Cy3-dUTP
  • DAPI
  • Olympus BX-51 microscope

Output Measurements

  • chromosome structure
  • translocation events
  • karyotype composition
