An investigated issue in biological and social sciences is understanding how behavioral and cultural traits, inherited from previous generations or produced in response either to changes in socioeconomic or ecological conditions, are spread in populations. Transmissions of behavioral traits have been observed in different animals like reef fish [1] and birds [2] and also between parents and their offspring [3]. Transmissions are due to social interactions and they are possible either between parents and their own offspring (vertically transmissions), between members of a cohort (horizontal transmissions), or between parents and offspring of others (oblique transmissions) [4, 5]. Modeling this kind of evolution results in the use of the basic format of the one-locus theory [6] in which the trait is a cultural one. Following the formalism of Rice [6], we consider an extension of one-locus theory in which a cultural (behavioural) trait is vertically transmitted from parents to their descendants.

Abstract

An investigated issue in biological and social sciences is understanding how behavioral and cultural traits, inherited from previous generations or produced in response either to changes in socioeconomic or ecological conditions, are spread in populations. Transmissions of behavioral traits have been observed in different animals like reef fish [1] and birds [2] and also between parents and their offspring [3]. Transmissions are due to social interactions and they are possible either between parents and their own offspring (vertically transmissions), between members of a cohort (horizontal transmissions), or between parents and offspring of others (oblique transmissions) [4, 5]. Modeling this kind of evolution results in the use of the basic format of the one-locus theory [6] in which the trait is a cultural one. Following the formalism of Rice [6], we consider an extension of one-locus theory in which a cultural (behavioural) trait is vertically transmitted from parents to their descendants.
