Concluding Comments Many other examples of this phenomenon could be cited, but the key points to emphasize are that genes are the primary regulators of developmental processes, their protein products…

Genes and Environment in Development Developmental Genetics Development results from the action of genes interacting with cellular and environmental cues. The gene products involved include transcriptional regulators, diffusible factors that…
