Are genetics an important study for STEM jobs?

There are many STEM areas where genetics is minimally if at all relevant to most research, deep space telemetry or pure mathematics for instance. That said, I personally think having a basic understanding of genetics is important to any scientist. Also, some questions will likely require cross-field expertise to solve, such as how all genetic info needed in one's lifetime is built into the submicroscopic structures of DNA, how methylation affects DNA transcription during different life stages, and how the body "knows" how to transcribe DNA coding into proteins and then into muscles, nerves, tissues, etc.
