On "Reflexive Selection"

Some natural populations show an extremely high degree of polymorphism, especially in color and pattern, which may be interpreted as "protective variation." Two possible genetic models, one based on frequency-stat (like thermostat) and one based on higher selection value of heterozygotes,...

Summary:Some natural populations show an extremely high degree of polymorphism, especially in color and pattern, which may be interpreted as "protective variation." Two possible genetic models, one based on frequency-stat (like thermostat) and one based on higher selection value of heterozygotes, have been proposed to account for the phenomenon.
