Origin
This strain with Downunder (Du) mutation is originated from a male fancy rat (Coming Home. This rat was introduced from U.S.A. on July 13th, 2005.). F1 generation was obtained by crossing with TM/Kyo female. A F3 male rat (#313) was crossed with WTC/Kyo and we obtained F3+1 (18/10/2006). The sperms were collected from a F3+4 rat.
Strain Characteristics
Heterozygous rats (downunder rat) have patchy pattern on their back and the same pattern is also obserbe on their abdominal skin hair. This rare hair color pattern is observed when they have a hooded mutation. This phenotype is dominant inheritance and homozygous rats are embryonic lethal.
Breeding Conditions
maintained by crossing between Du/+ (downunder) and +/+ (hooded). Tyrosinase allele: C/C
Genotyping
The causative gene is unknown.
