The kanji 性 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of the radical 心 (kokoro, meaning "heart" or "mind") and the phonetic component 生 (nama, meaning "life" or "birth"). The combination suggests the inherent nature or character that is "born" from the "heart" or "mind". It originally depicted the inherent nature or disposition of something, and its meaning expanded to include "sex" or "gender" over time.
