    Notes: [Auszug] The new gene is semi-dominant and behaves in every way as would be expected of a totally sex-linked gene with no homologue on the F-chromo-some, though the numbers of mice bred are not yet enough to detect minor deviations from expectation. There are three phenotypes in females,-corre-sponding to ...

    Description / Table of Contents: Zusammenfassung 1. Tabby (Ta) ist ein völlig geschlechtsgebundenes Gen in der Hausmaus. In Weibchen zeigt es unvollkommene Dominanz. Männchen mit dieser Mutante gleichen homozygoten Weibchen, ein Beweis, daß das Y-Chromosom kein homologes Gen enthält. 2. Heterozygote Weibchen haben schwarze Querstreifen, die nur auf Agouti-Hintergrund erkennbar sind. Homozygote Weibchen und hemizygote Männchen zeigen eine Anzahl von Abnormitäten, die genau den von dem recessiven Autosomalfaktor crinkled hervorgerufenen gleichen. 3. Brindled und Mottled sind gleichfalls völlig geschlechtsgebunden; das geht hervor aus Koppelungsversuchen mit Weibchen, die heterozygot für Tabby und eines dieser Gene sind. Sowohl Brindled und Mottled haben Tabby gegenüber eine Rekombinationshäufigkeit von ungefähr 4%. Das beweist das Vorkommen von crossing-over in dem Differentialsegment des X-Chromosoms in Weibchen.
    Notes: Summary 1. A totally sex-linked gene, Tabby (Ta), in the house mouse is described. It is semi-dominant in females. Mutant males resemble homozygous females, which shows that there is no homologue on the Y-chromosome. 2. Heterozygous females have transverse black markings, visible only in agoutis. Homozygous females and hemizygous males have a number of defects exactly resembling those produced by the autosomal recessive crinkled. 3. Brindled and Mottled are shown also to be totally sex-linked, by means of linkage tests with Tabby in doubly heterozygous females. Both Brindled and Mottled recombine with Tabby with a frequency of about 4%. This proves that crossing-over takes place in the differential segment of the X-chromosome in females.

    Description / Table of Contents: Zusammenfassung Die Reihenfolge der total geschlechtsgebundenen Gene und ihre Rekombinationshäufigkeit in heterozygoten Weibchen ist $$B_n - 11\% - Ta - 4\% - _{Mo}^{Br} $$ \ Rough (ro) liegt in Koppelungsgruppe V, zwischen pa und Sd und sehr dicht bei pa. Die Rekombinationshäufigkeit zwischen pa und ro ist ungefähr 0,6%.
    Notes: Summary The order of the totally sex-linked genes and the recombination frequencies in heterozygous females are — $$B_n - 11\% - Ta - 4\% - \left\{ {_{Mo}^{Br} } \right\}$$ Rough (ro) is located in linkage Group V, between pa and Sd and very close to pa. Recombination frequency between pa and ro is about 0.6%.

    Notes: Zusammenfassung Es wurde ein neues Gen der Tanzmausgruppe beschrieben mit den Symptomen Hyperaktivität, Kopfschütteln und Tanzen und Taubheit. Die Abnormalität trat bei 4 Jungen in einem Wurf freilebender wilder Hausmäuse auf, mit größter Wahrscheinlichkeit spontan. Kreuzungsversuche zeigten, daß die Abnormität durch ein rezessives Gen mit vollständiger Penetranz verursacht wird. Die neue Mutation ist nicht identisch mit v, sh-1, sh-2, je, kr, pi oder fi. English Summary. A new gene with the typical phenotype of the waltzer-shaker group is described. The name dreher, with symbol dr, is proposed. It arose, presumably by spontaneous mutation, in the wild, and was obtained in a litter of four, all of which were homozygotes, captured in a factory in Detmold, Germany. The gene is recessive and good single-factor segregations were obtained. Non-identity with v, sh-1, sh-2, je, kr, pi, and fi was proved.
