First of all, desired chromosomes are broken into several segments with xrays, after which they are implanted in rodent cells, which clone the chromosomes. Pdf radiation hybrid rh mapping, a somatic cell genetic technique, was developed as a general approach for constructing longrange. Radiation hybrid rh mapping is a convenient and widely used method for rapidly locating new dna sequences on genomes in relation to other dna markers. It is based on a statistical method to determine not only the distances between deoxyribonucleic acid dna markers but also their order on the chromosomes. Comparative rh mapping of 24 orthologous genes in this study revealed internal structural rearrangements between human chromosome 17 hsa17 and bovine chromosome 19 bta19, two chromosomes known. Genome mapping with radiation hybrids is based on works of goss and harris, which were not only a. Pdf application of aflp technology to radiation hybrid. Radiation hybrid rh mapping provides a powerful tool for determining order of genes in genomes for which genebased linkage mapping is impractical. Contribution of radiation hybrids to genome mapping in. Radiation hybrid mapping an overview sciencedirect topics.

Radiation hybrid mapping is a technique for mapping mammalian chromosomes. Radiation hybrid mapping has emerged in the end of the 1990 s as a successful and complementary approach to map genomes, essentially because of its ability to bridge the gaps between genetic and. Radiation hybrid mapping also known as rh mapping is a technique for mapping mammalian chromosomes radiation hybrid mapping consists of several steps. The original order of these fragments to each other is determined by ascertaining that specific dna sequences are found to be in the same clones, which means that they segregate together because of their close physical proximity in the genome. Radiation hybrid rh mapping is the most efficient method for generating longrange genomic maps using both polymorphic and nonpolymorphic markers. We have investigated the use of aflp technology as a tool for the high throughput enrichment of radiation hybrid rh maps. Prospects of mapping genes and genomes using rh mapping.

A rh panel incorporating at least 20% of the donor genome per hybrid is necessary for efficient map generation. A major effort utilizing radiation hybrid mapping has recently provided a good framework for integrating the position of genes with respect to the genetic linkage maps. There are a number of advantages to radiation hybrid mapping.

Radiation hybrid mapping is based on this artificially induced random breaking of the genomic dna into smaller fragments. Radiation hybrid mapping is a method that combines aspects of both genetic and physical mapping and is extensively used in the construction of wholegenome maps.
