What determines where a tree grows its branches, and what their shape will be? Is it genetically predetermined or are there other factors at play?
In: Biology
Genetics play an important role, but don’t give detailed information about placement by them selves. You can view genetics as giving a bunch of guide lines for how an organism should be constructed. When the organism is exposed to the environment sun, moisture, temperature change etc. It will respond in accordance with it’s genetics. However in many cases the systems governing the precise response like exactly where a new branch will form are so complicated that they have a partially random character. So we can predict roughly when and where a new branch forms but not exactly
