Abstract
It is important to understand the dynamics of biological information in a genetic population for it determines the dynamics of energy and, thus, of matter. In another work we have initiated the characterization of a genetic population transmitting information from one generation to the next. In this work the genetic information flow under selection is analyzed in a genetic population under random mating. A one-locus diallelic model has been utilized in the derivations. Based upon the Schmalhausen's model of information circulation and the Shannon's theory of information we have focused on the analysis of information flow in the stage of transformation under the input of selective forces. The measures of information are important parameters to take account of when the process of populational evolution is analyzed. Several expressions relating information measures with selection coefficients corresponding to each genotype have been obtained. They are conditional entropies and mutual information (information transfer). Finally, a numerical survey employing a great deal of fitness values has been performed.
