White-eye can refer to:
- White-eye (Zosteropidae), a large family of birds.
- White-eye (fish) (Oxyzygonectes dovii), a species of fish.
- White-eye mutation, a mutation in Drosophila melanogaster linked to the X chromosome, found by reciprocal cross breeding experiments in 1906.
- A lioness member of the Marsh Pride of lions that have featured for many years in the BBC series Big Cat Diary
- Griefer, a disruptive player of MMORPGs in Taiwan is known as "white-eyed"
The white-eyes are small passerine birds native to tropical, subtropical and temperate Sub-Saharan Africa, southern and eastern Asia, and Australasia. White-eyes inhabit most tropical islands in the Indian Ocean, the western Pacific Ocean, and the Gulf of Guinea. Discounting some widespread members of the genus Zosterops, most species are endemic to single islands or archipelagos. The silvereye, Zosterops lateralis, naturally colonised New Zealand, where it is known as the "wax-eye" or tauhou ("stranger"), from 1855. The silvereye has also been introduced to the Society Islands in French Polynesia, while the Japanese white-eye has been introduced to Hawaii.
The white-eye is a species of killifish of the family Anablepidae. This species is the only member of its genus, Oxyzygonectes, and the subfamily Oxyzygonectinae.
white, abbreviated w, was the first sex-linked mutation ever discovered, found in the fruit fly Drosophila melanogaster. In 1910 Thomas Hunt Morgan and Lilian Vaughan Morgan collected a single male white-eyed mutant from a population of Drosophila melanogaster fruit flies, which usually have dark brick red compound eyes. Upon crossing this male with wild-type female flies, they found that the offspring did not conform to the expectations of Mendelian inheritance. The first generation produced 1,237 red-eyed offspring and three white-eyed male flies. The second generation produced 2,459 red-eyed females, 1,011 red-eyed males, and 782 white-eyed males. Further experimental crosses led them to the conclusion that this mutation was somehow physically connected to the "factor" that determined sex in Drosophila. This led to the discovery of sex linkage, in which the gene for a trait is found on a sex chromosome. Morgan named this trait white, now abbreviated w. Flies possessing the white allele are frequently used to introduce high school and college students to genetics.
