Abstract
The recognition of the phenomenon of dominance is as old as the Mendelian theory itself; there still does not appear to be, however, anything approaching general agreement on the reason for its existence (cf. Crosby (1963), Clark (1964), Ford and Sheppard (1965), Wright (1964)). In this chapter an account is given of the theory of Fisher, the discussion of which is largely quantitative, that dominance appears as a result of natural selection. In this context, to say that A1 is dominant to A2 is to say that the heterozygote AXA2 is indistinguishable in all respects from the homozygote AA in. particular it follows that the heterozygote has the same fitness as this homozygote.
