Genes

Gene	Allele	Assay Type	Description
Tyrp1	Tyrp1^b
Ifna		Southern analysis	pMF1204
Ifnb1		Southern analysis	pM(beta)-3

Notes

• Experiment
  Two offspring classified as M. spretus type displayed a variant in one of the Ifa restriction fragments. These variants may represent a recombination within the Ifa locus or a mutation in one of the M. spretus progenitor males.
