The registered pedigree stuffed animals of the present invention are stuffed toy animals which are made according to a method which simulates the biological laws of inheritance and which provides documentation certifying the pedigree status of the toy animals, both for educational, recreational and aesthetic purposes. According to the method a pair of opposite sex âparentâ toy animals are sold together with a serial number by which the parents genotype and phenotype may be identified. The owner or owners of the âparentâ toy animals may register the parents with the manufacturer and subsequently request âbreedingâ of the animals, whereupon the manufacturer makes at least one âoffspringâ toy animal randomly selected from a litter having phenotypes determined according to the registered genotypes of the parents and the Mendelian laws of inheritance. In an alternative embodiment, the parents serial numbers may encode six traits, and one offspring may be produced according to the laws of inheritance.
