Genetic interactions (epistasis) can often confound simple interpretations of such "knock-out" studies.
Molecular biology is the study of molecular underpinnings of the process of replication, transcription and translation of the genetic material.

"In the genetic algorithm literature, parameter interaction is called epistasis (a biological term for gene interaction). When there is little to no epistasis, minimum seeking algorithms [i.e., hill-climbers --A.M.] perform best.
