FAQ
Frequently Asked Questions
No. A chromosome map details a single chromosome. A genome map encompasses all chromosomes of an organism.
A genetic map (linkage map) shows order based on recombination rates (centimorgans). A physical map shows the actual physical distance in base pairs or based on overlapping DNA fragments.
The concept is fundamental, but the term is often subsumed under more specific terminology like 'genome assembly', 'annotation', or simply 'map' within a clear genomic context.
Alfred Sturtevant, a student of Thomas Hunt Morgan, constructed the first genetic (linkage) map of the fruit fly Drosophila melanogaster in 1913.
A diagram representing the relative positions of genes or other loci along a chromosome.
Chromosome map is usually scientific / technical in register.
Chromosome map: in British English it is pronounced /ˈkrəʊ.mə.səʊm ˌmæp/, and in American English it is pronounced /ˈkroʊ.mə.soʊm ˌmæp/. Tap the audio buttons above to hear it.
