Evolutionary Limits and Constraints

Genes have an enormous potential for pleiotropic effects because proteins encoded by genes are embedded in networks of interacting biochemical processes, and these networks in turn are likely to influence the expression of multiple traits. Moreover, genes that regulate the expression of other genes ...
