Olfactory discrimination of urinary odortypes from congenic strains (DBA/1Bg and DBA1.C57BL10-YBg) of mice differing in their Y chromosomes.
Differential effects of one or more genes in the nonpseudoautosomal region of the DBA1 and C57BL10 Y chromosomes on offensive attack may be mediated, at least in part, by differential effects of this Y chromosomal gene(s) on the sending and receiving of discriminable urinary odortypes. This hypothesis is based, in part, on the report that urine from a pair of Y chromosomal congenic strains (C57BL6.AKR-Y and C57BL6) of mice can be discriminated in a Y maze test. The AKR and C57BL6 Y chromosomes come from two distinct species of mouse (Mus domesticus and Mus musculus, respectively). Thus, this Y chromosomal variant exists between mouse species. The DBA1 and C57BL10 Y chromosomes come from a single species, Mus musculus. Here we show that in the Y maze system previously used, urine from mice with the DBA1 and with the C57BL10 Y chromosomes can also be discriminated. Thus, there are discriminable urinary odortypes for this pair of Y chromosomes from the same species, Mus musculus.
