Science - Genetics
Additional field(s): Biology (-tech,-chem,micro-) | | English term or phrase: gene mapping | Definition from Oak Ridge National Laboratory :
Determination of the relative positions of genes on a DNA molecule (chromosome or plasmid) and of the distance, in linkage units or physical units, between them.
Example sentence(s): - Over the last decade, there has been marked progress in gene mapping in man and some animals. Advances in gene mapping have also touched fur-bearing animals: the genetic map of mink consists of 74 genes marking all chromosomes, except the Y, and the fox map contains 35 genes marking 15 of 16 autosomes and the X chromosome. AgBiotechNet
- Pioneering gene mapping studies into the genomes of fishes will only serve as the starting point for more detailed studies into the function of these genomes. Future research directed at understanding the mechanisms of gene actions and interactions will benefit all areas of biology, including ecology, ethology, evolution, and physiology. CAT.INIST
- Somatic cell hybrid (SCH) panels and radiation hybrid (RH) panels are powerful resources for comparative gene mapping because gene assignments are made without the detection of genetic polymorphism as needed for linkage mapping. Genome Research

| رسم أو وضع الخريطة الجينية | Definition:
"Gene mapping" refers to the mapping of genes to specific locations on chromosomes. It is a critical step in the understanding of genetic diseases. There are two types of gene mapping:
Genetic Mapping - using linkage analysis to determine the relative position between two genes on a chromosome.
Physical Mapping - using all available techniques or information to determine the absolute position of a gene on a chromosome. |

Definition from own experience or research:
الخريطة الجينية هي عبارة عن تحديد الموقع النسبي للجينات على جزئ الحامض النووي الريبوزي منقوص الأكسجين وكذلك المسافة بين الجينات عن طريق وحدات الإرتباط أو الوحدات الفيزيائية.
