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:
“Those feelings of envy are familiar to many of us. We see our children accomplishing things that we’ve always been afraid to try, or we give them opportunities that we never had, and we find ourselves feeling jealousy mixed with our pride, or we feel resentful when they take it all for granted.”
—Ruth Davidson Bell (20th century)
