chromosome mapping
Definition
Noun 1. (Genetics) The process of determining the relative positions of genes on a chromosome and the distance between them. It involves creating a map that shows the linear order of genes or other genetic markers along a chromosome.
Usage
- Chromosome mapping is a fundamental technique in genetics.
- The completion of the Human Genome Project relied on detailed chromosome mapping.
- Researchers use chromosome mapping to identify genes associated with hereditary diseases.
Advanced Usage
- Linkage mapping: A type of chromosome mapping that determines the relative positions of genes based on how often they are inherited together.
- Physical mapping: A type of chromosome mapping that determines the absolute physical positions of genes or markers on a chromosome, often measured in base pairs of DNA.
Variants and Related Words
- Gene mapping (n): Often used synonymously with chromosome mapping, specifically focusing on locating genes.
- Genetic map (n): The diagram or result produced by the process of chromosome mapping.
- Map (v): In genetics, to perform the act of chromosome mapping (e.g., "to map a gene").
Synonyms
- Gene mapping
- Genetic mapping
Related Terms (Not Synonyms)
- Genome sequencing: Determining the complete DNA sequence of an organism's genome, a more detailed process that often builds upon mapping data.
- Linkage analysis: The method used to create a linkage map.
Noun
-
