Co-segregation of intermale aggression with the pseudoautosomal region of the Y chromosome in mice.
The sexual dimorphism of aggression has led to a search for its Y chromosomal correlates. We have previously confirmed that initiation of attack behavior against a conspecific male is Y-dependent in two strains of laboratory mice (NZB and CBA/H). We provide evidence that the non-pseudoautosomal region of the Y is not involved and that only the pseudoautosomal region of the Y is correlated with initiation of attack behavior. The autosomal correlates also contribute to this behavior in an additive or interactive manner with the pseudoautosomal correlates.
