Their impact is upon the distribution of offspring produced by any given parents. These parameters are typically set before beginning search, are held constant for the whole run, and are applied invariantly in all situations. Selection and polygenic characters . A transmission function describes the probability distribution of offspring from every possible pair of parents. Selection and polygenic characters .
Selection merely chooses from among the options made available by variation.
The continued creativity of the evolutionary process is dependent upon the production of novel offspring that are differentially favored by selection. Selection and polygenic characters . With this approach, it is possible to extract features that are essential for the performance of GAs which have nothing to do with schemata. Slatkin, M. 1970. Selection and polygenic characters .
