Temperature of the water.

Explanation: temperature is an external (environmental) factor that can alter gene expression (e.g., temperature‑sensitive enzymes, heat shock response). Sex and organ are intrinsic/biological factors (and organ is a tissue‑specific context), while "number of organisms in the group" describes population density/social context — which can influence gene expression but is less commonly given as a simple environmental example than temperature.
