In many desktop Networked Virtual Reality applications, anavatar must be chosen to represent the user within the virtualenvironment. Usually, the number of avatars one can select is verylimited. Therefore, combinations of hair color, cloth texture, andskin color are used to increase the selection space. In this paper,human reproduction is mimicked to produce an unlimited numberof avatars, which inherit traits from two parents. The meshes of allavatars are constructed based on control parameters that aredistributed as genes among a group of chromosomes. Hence, theimplementation consists of a pre-selected distribution ofcharacteristics, represented as control parameters, over a predeterminednumber of chromosome pairs for both parents;followed by a simulation of the father's and mother's gametesgeneration; which are randomly combined in a simulatedfecundation. The diversity is ensured in three random processes:1) random exchange of segments during crossover; 2) randomalignment of homologous chromosomes at metaphase I ofmeiosis; and 3) random union of male and female gametes duringfecundation.
