Genetic Variation: Blind, Directed, Interpretative?
Journal Title: Filozoficzne Aspekty Genezy - Year 2008, Vol 5, Issue 0
Abstract
The article brings up the issue of genetic variability source. Two causes of that variability are genetic mutations and sexual reproduction. The authors generally focus on the mutations. The issue of sexual reproduction is concerned only as an introduction. Mixing of genes from non-identical parents, transmission of different genetic material to every descendant, and recombination of genes in the crossing-over process are the main effects of sexual reproduction. As for genetic mutations, authors say that in addition to entirely blind genetic variation and absolutely directed physiological reactions of organism there is a whole spectrum of processes which should be placed somewhere between these two extremes. The basic part of this text refers to this particular third type of mutations – not exactly random but, at the same time, not entirely determined.
