Abstract

In this paper, we introduce gonosomic algebras to algebraically translate the phenomenon of genetic sterility. Gonosomic algebras extend the concept of gonosomal algebras used as algebraic model of genetic phenomena related to sex-determination and sex-linked gene transmission by allowing genetic sterility to be taken into account. Conditions under which gonosomic algebras are not gonosomal and several algebraic constructions of gonosomic algebras are given. To each gonosomic algebra, an evolution operator noted W is associated that gives the state of the offspring population at the birth stage. Next from W we define the operator V which gives the frequency distribution of genetic types. We show that the various stability notions of equilibrium points are preserved by passing from W to V .
