Gene action is called "cell-specific" if the expression of a particular gene is limited to a definite cell system, and "phase-specific" if the manifestation is limited to a definite developmental period. Both phenomena are consequences of differential gene activation. The action of a particular gene is "sex-limited" if the corresponding phenotypic character is realized in only one of the sexes. "Sex-controlled" gene action is a type of action characterized by the different expression of a gene in male and female organisms. Genes showing either sex-limited or sex-controlled manifestation may be localized either in sex-chromosomes or autosomes.  1, fiche 1, Anglais, - gene%20action
