Abstract

The intermale aggression of the B1OD1F1 hybrid resembles that of the pugnacious DBA/1 strain, whereas the intermale aggression of the B1OD2F1 hybrid resembles that of the pacific C57BL/10 strain. This finding is consistent with the hypotheses that the DBA/1 (but not the DBA/2) Y chromosome has an effect on intermale aggression or that the DBA/2 autosomes mask a potential contribution of the DBA/2 Y chromosome to intermale aggression. These two hypotheses were discriminated by testing intermale aggression in DBA/1, DBA/2, and DBA/2.DBA/1-Y congenic strains. The DBA/2 and DBA/2.DBA/1-Y were statistically equivalent on all measures of intermale aggression. This finding supports the hypothesis that the DBA/1 and DBA/2 Y chromosomes have the potential for equivalent effects on intermale aggression and that the DBA/2 autosomal genes can mask the potential contribution of the DBA/1 and DBA/2 Y chromosome to intermale aggression.
