Genetic and physical maps illustrate the arrangement of genes and DNA markers on a chromosome. The relative distances between positions on a genetic map are calculated using recombination frequencies while a physical map is based on the actual number of nucleotide pairs between loci. These maps are...
The alignment of genetic and physical maps presented here should facilitate the continued analysis of essential genes in Arabidopsis and further characterization of a broad spectrum of mutant phenotypes in a model plant. 展开 关键词: Arabidopsis DNA, Bacterial Genetic Techniques Chromosome Mapping Cloning...
We have also completed the constiuction of a first generation physical map with a total of 2,117 YAC clones assigned to unique locations on the chromosomes and covering more than half of the rice genome. At present, we are using the information from these maps for tagging several key ...
Genome-wide integrated genetic and physical maps have provided powerful tools and infrastructure for advanced genomics research of human and other animal and plant model species. They are not only crucial for large-scale genome sequencing, but also provide powerful platforms required for many other asp...
What is the difference between physical and genetic maps of chromosomes and how are genetic maps constructed?Chromosomes:Apart from gamete cells and red blood cells, all body cells contain an identical copy of the entire complement of the individual's genetic...
Pulsed-field gel electrophoresis (PFGE) is a useful tool for analysis of differences in the genome structure of many strains, and over a hundred of genome maps have been constructed. Our previous PFGE analysis of B. fragilis revealed an apparent difference between the genome structures of type ...
Genetic/physical mapping and QTL detection Genetic maps (or linkage maps) indicate the position and relative genetic distances between markers along chromosomes, based on the principle that markers segregate during meiosis as a result of chromosome recombination (Paterson1996). Genetic mapping is the fi...
Fig. 3: A genetic linkage map based on a F2 offspring bred from iM line and iBS90. The markers were labeled by the scaffold # followed by the physical position of the SNP. Markers in red represent those markers used for validation by Sanger sequencing. ...

172 mapped markers were absent in the current B73 assembly and their placement can be used for future improvements of the B73 reference sequence. Colinearity of the genetic and physical maps was mostly conserved with some exceptions that suggest errors in the B73 assembly. Five major regions ...
