Norway Ratoups (this falls to the rabbit) because most of the linked genes belong to one system. Some 40 to 45 mutant gene/loci have been described and 35 have featured in studies of linkage and independent assortment. A detailed discussion of the early work in linkage may be found in Robinson (1960); while a

Rabbits has reflected upon the rate of discovery of mutants for the species and upon the number of known linkage groups. Despite this, the rabbit still remains a useful research animal for a variety of topics. Some 45–50 mutant gene/loci have been reported, of which 34 have been employed in studies of ind

Guinea-Pigerly, the animal has receded from favour. In spite of several systematic searches for possible linkage among the known mutants, the results have been largely negative. However, even negative results are not devoid of value since these imply that a variety of chromosome segments are tagged by genes.

Deermouses old-world house mouse. However, for a number of reasons, some technical but mostly arising from lack of opportunity, the deermouse has not been utilized as extensively as its innate reproductive and genetic qualities would merit. Some 40–46 mutant gene/loci are known, of which 21 have been involve

Cataid to the more formal aspects of the species’ genetics. About 20 mutant genes have been described but few of these have featured in studies on their possible linkage relationships. A detailed account of these mutants and of the animal’s genetics may be found in Robinson (1959, 1971).

Dogedity of coat colour has received considerable attention and a number of loci have been defined. However, there is controversy over the status of certain colour variations and recognition of several genes (Winge, 1950; Little, 1957; Burns and Fraser, 1966). A large number of abnormalities have been

In most cases, sufficient breeding data have been published to establish the mode of inheritance of individual mutants but little on the possible linkage relationships between the mutants.
