Chromosome in situ hybridization
WebMar 9, 2024 · Fluorescence in situ hybridization (FISH) was developed more than 30 years ago and has been the most paradigm-changing technique in cytogenetic research. FISH has been used to answer questions related to structure, mutation, and evolution of not only individual chromosomes but also entire genomes. FISH has served as an … WebGenomic in situ hybridization (GISH), which uses total genomic DNA as a probe, is a powerful tool for determining the origin of genomes or chromatin in hybrids. This technique successfully detected barley chromosomes in hybrids with wheat (Mukai and Gill, 1991; Schwarzacher et al. 1992).
