Genetic and molecular analyses of developmental and physiological processes in numerous experimental systems have recently revealed unsuspected levels of complexity within genetic regulatory pathways. Perhaps most surprising is the result that loss-of-function mutations engineered within many regulatory genes have little or no effect on phenotype. Although the lack of phenotype suggests that these genes are not essentia1 to the processes under consideration, new evidence indicates that these… CONTINUE READING
