Strain Description

Phenotype
There is distinctly diluted dorsal pelage due to clumping of pigment granules occurs in the proximal portion of the hair. The undercoat is not as light as in silver. An overall platinum-gray color in the subadult molt deepens into the diluted tan-gray of the adult. The dorsal body hairs, when parted, appear to be white at the base. Dark-tipped hairs are present, particularly on the head, but are reduced in number. The ears are pale colored and the tail stripe is pale and less distinct. Scrotal pigment is lacking. The eyes are dark, but have a reddish-brown cast. Contrasted with silver, the pelage, when parted, is tricolored, having a gray subterminal band.

MMRRC Genetic QC

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@missouri.edu. Older strains may not have this information.

Availability Level

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.
