Gene Information

Genetic Alterations
Spontaneous mutation
Genotype Determination
Wide-band agouti coat color is more yellow than the wild type of P.m. bairdii. The agouti bands of the individual hairs are lengthened relative to the total hair, and there is a corresponding reduction in the number of all-black guard hairs. The phenotype superficially resembles yellowing, which is a recessive trait, but usually can be distinguished by the greater number of dark guard hairs in wide band. The dorsal-ventral line of demarcation is not as distinct in wide band as in yellowing.
Strain Development
Source: The wide band allele has a high frequency in P.m. nebrascensis of the Nebraska sandhills, where the phenotype is typical of the subspecies. The wide-band variant was established from P.m. nebrascensis and maintained in laboratory stocks derived by repeated backcrossing to P.m. bairdii wild-type. Progeny, as expected, segregate 1:1.

Order Request Information

Male mice were obtained from the Peromyscus Genetic Stock Center as part of a long term project to develop cropreservation techniques for Peromyscus. Sperm have been cryopreserved and are available. However, cryorecovery techniques have yet to be developed.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.
