Abstract
An interspecific backcross between lab mice and Mus spretus was used to construct a multilocus map of Chromosome 17 consisting of 12 new anonymous loci and 9 anchor loci. In addition, 7 anonymous DNA loci were added to the Chr 17 map for the BXD strains. Although we were able to identify readily the most likely gene order in the interspecific backcross, we found no evidence for an unambiguous gene order using the BXD recombinant inbred strains. Comparison of the interspecific backcross map and the BXD RI strain map revealed evidence in the interspecific backcross for a longer total genetic length, enhanced recombination distal to H-2, a segment showing suppressed recombination, and strong interference.

Abstract
The t complex on chromosome 17 of the house mouse is an exceptional model for studying the genetic control of transmission ratio, gametogenesis, and embryogenesis. Partial haplotypes derived through rare recombination between a t haplotype and its wild-type homolog have been essential in the genetic analysis of these various properties of the t complex. A new partial t haplotype, which was derived from the complete tw71 haplotype and which is called tw71Jr1, was shown to have unexpected effects on tail length and unique recombination breakpoints. This haplotype, either when homozygous or when heterozygous with the progenitor tw71 haplotype, produced short-tailed rather than normal-tailed mice on certain genetic backgrounds. Genetic analysis of this exceptional haplotype showed that the recombination breakpoints were different from those leading to any other partial t haplotype. Based on this haplotype, a model is proposed that accounts for genetic interactions between the brachyury locus (T), the t complex tail interaction (tct) locus, and their wild-type homolog(s) that determine tail length. An important part of this model is the hypothesis that the tct locus, which enhances the tail-shortening effect of T mutations, is in fact at least two, genetically separable genes with different genetic activities. Genetic analysis of parental and recombinant haplotypes also suggests that intrachromosomal recombination involving an inverted duplicated segment can account for the variable orientation of loci within an inverted duplication on wild-type homologs of the t haplotype.

Abstract
The levels of sn-glycerol-3-phosphate dehydrogenase (GPDH) were determined in the brown adipose tissue (BAT) of different inbred strains of mice. The BAT of the BALB/cJ strain contains twice as much enzyme activity per milligram protein as do other strains. The appearance of this difference is developmentally dependent, since it is not detected in BAT until 25-30 days postpartum. Genetic analysis of this strain difference has shown that the mechanism of inheritance involves at least two genes, one of which is linked to the Gdc-1 structural locus on chromosome 15. Determinations of GPDH synthesis by immunoprecipitation of GPDH protein labeled in vivo with [3H]leucine, and of GPDH mRNA by Northern blot analysis, establish that in BALB/cJ mice higher rates of enzyme synthesis are determined by elevated levels of GPDH mRNA. It was also found that cold stress increases GPDH mRNA levels in all the strains examined.

Abstract
sn-Glycerol-3-phosphate dehydrogenase (glycerol-P dehydrogenase, EC 1.1.1.8) activity levels in seven tissues of adult mice vary approximately 100-fold from a low of 0.1 unit/mg of protein in the cerebral cortex to a high of 8 units/mg of protein in the brown fat of cold-adapted mice; the brown fat accounts for approximately 1% of the total tissue protein. This high degree of variation in the quantitative expression of an enzyme in different tissues has provided us with a system for analyzing the mechanism by which tissue specific variation for a given gene product is controlled. To this end we have measured the amount of immunoreactive enzyme and the level of translatable glycerol-P dehydrogenase mRNA and have localized the glycerol-P dehydrogenase-positive cells by immunocytochemistry. We have found that the amount of enzyme protein in a tissue is strongly correlated with the level of its translatable mRNA (correlation coefficient = 0.996) and that in several cases the differences among tissues can be explained by differences in the numbers of glycerol-P dehydrogenase-positive cells.
