Mouse Cytogenetics

Welcome to our Cytogenetics resources page. The links on the left provide access to images and information on chromosome exsisting within humans, mice,and horses. The idiogram pages provide quick access to a select part of the chromosome. The Genome Machine provides a graphical interface to the Online Mendielian Inheritance in Man(OMIN) database. Mouse and Human spreads are provided under the chromosome spread links. Finally, mouse cytogenetics provides a link to information about the mouse genome.


The Idiogram Album files are PortableDocumentFormat(.pdf) versions of standard idiograms. These PDF files were created to be compatible with graphics software such as Adobe Acrobat Reader. The Human set is based on the ISCN 1985 High Resolution Banding (ISCN 1985: An International System for Human Cytogenetic Nomenclature, Harden, D.G. and Klinger, H.P., eds., published in collaboration with Cytogenet. Cell Genet., Karger, Basel, 1985). Each human file contains idiograms for three resolutions of banding (400, 550, 850 total bands).The mouse set is adapted from Nesbitt and Francke (Chromosoma 41:145-158, 1973) and Edward Evans' standard karyotype from Lyon & Searle "Genetic variants & strains of the laboratory mouse" 2nd edition, OUP 1989. The following people have contributed ideas, suggestions and banding opinions: Christine Disteche and George Martin of the Department of Pathology, University of Washington; Roland Hubner, University of Liege.
