The different mechanisms of outbreeding depression can operate at the same time. However, determining which mechanism is likely to occur in a particular population can be very difficult. There are three main mechanisms for generating outbreeding depression: Fixed chromosomal differences resulting in the partial or complete sterility of F 1 ...

Rank theory is an evolutionary theory of depression, developed by Anthony Stevens and John Price, and proposes that depression promotes the survival of genes. [1] Depression is an adaptive response to losing status (rank) and losing confidence in the ability to regain it. The adaptive function of the depression is to change behaviour to promote ...
