If a population is constrained to exhibit no variation in the allelic frequency distribution of any gene then information may only be recorded by recombining genes into new configurations (schemata). It is shown that such a constraint need lead to no loss of information capacity. A simple algorithm, employing direct replacement and a single uniform genetic operator, is then analysed with regard to schema sampling. The probabilities of schema creation and destruction are proven identical, regardless of operator. The probabilities are then deduced, with which new schemata are sampled by, first, recombination, and, second, mutation, in relation to order and allelic variation. The analysis overcomes limitations inherent in earlier work [4, 9,
