Abstract
Genetic analysis of a proposed cis-acting temporal locus (Adh-3t), which regulates alcohol dehydrogenase C2 (ADH-C2) activity in mouse epididymis extracts, among F1 (ddN .times. BALB/c) .times. ddN male backcross progeny provided evidence for genetic distinctness between the structural (Adh-3) and temporal (Adh-3t) loci on chromosome 3. Genetic analysis also confirmed the close linkage of Adh-1 (encoding liver and kidney ADH-A2) and Adh-3 (encoding stomach ADH-C2) to within 0.3 centimorgans on the mouse genome. Evidence is presented for a proposed closely linked cis-acting temporal locus (designated Adh-1t) for the A2 isozyme (encoded by Adh-1) controlling the activity of this enzyme in mouse kidney extracts, but having no apparent affect on liver and intestine ADH-A2 activities. An extensive survey of the distribution of Adh-1, Adh-3 and Adh-3t alleles among 65 strains of mice is reported, with the exception of 2 Japanese strains (ddN and KF), linkage disequilibrium between Adh-3 and Adh-3t was observed. Sex differences in mouse liver and kidney ADH-A2 activities were observed with male/female ratios of approximately 0.6 and 3, respectively, for these tissue extracts.
