TL;DR: Thirteen biochemical groups of wild mice from Europe, Asia, and Africa belonging to the genus Mus are analyzed at 22–42 protein loci and Phylogenetic trees are proposed and patterns of biochemical evolution are discussed.

TL;DR: The findings suggest that the strains NZB and NZC stemmed from a European founder stock which differed from the ancestral stocks of other laboratory strains and that the ancestral mice of the RR strain had been transported from China to Japan.

TL;DR: Estimates of genetic distances between the various races and subspecies were obtained by comparing cleavage maps of the mtDNAs with various restriction enzymes and suggest that M. molossinus is situated in a unique evolutionary position among Asian subspecies.

TL;DR: Observations, such as the expression of homogeneous Valpha 14-J alpha 281 in athymic mice, suggest that the positive selection of V alpha 14+ T cells occurs extrathymically.

TL;DR: Original recombinants whose breakpoints were defined by direct sequencing of PCR‐amplified DNAs were tested for the rate of secondary recombination in the crosses with laboratory strains in order to determine the location of such a genetic element and demonstrated that the chromosomal segment proximal to the hotspot is essential for enhancement of recombination.
