This is the genetic makeup of an organism that determines potential physical characteristics. It's like the blueprint for how an organism could look or behave.
This refers to changes in gene expression that don't involve alterations to the underlying DNA sequence. It's like having a light switch (the gene) and being able to turn it on or off (gene expression) without changing the wiring (DNA sequence).
This is a process by which organisms become better suited to their environment over generations through natural selection. It's like nature fine-tuning species so they can survive and thrive in their specific environments.
