Intraspecific competition leads to unequal resource partitioning among individuals. Skewness of weight distributions in even-aged populations of plants and animals may be considered as a result of unequal resource partitioning. Properties of the function describing resource partitioning used in the mathematical model of weight differentiation, which simulate all features of weight distributions, are presented. Several experiments which concern relations between competition, resource partitioning and weight distributions are discussed, together with some population consequences of individual inequality.
