Genotype: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.
Epigenetics: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).
Adaptation: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.
