Sexual jealousy is a special form of jealousy in sexual relationships, present in animals that reproduce through internal fertilization, and is based on suspected or imminent sexual infidelity. It is founded on the instinct of keeping genes in the gene pool and expecting sexual partners to care for the offspring. The concept is studied in human and non-human primates in the field of evolutionary psychology.

Famous quotes containing the word jealousy:
“The hood-winked husband shows his anger, and the word jealous is flung in his face. Jealous husband equals betrayed husband. And there are women who look upon jealousy as synonymous with impotence, so that the betrayed husband can only shut his eyes, powerless in the face of such accusations.”
—J. August Strindberg (1849–1912)
