Unlike humans, the sex and physical appearance of fruit flies is not influenced by hormones. [16] The appearance and sex of fruit flies is determined only by genetic information. [16] Female fruit flies are substantially larger than male fruit flies, with females having bodies that are up to 30% larger than an adult male. [17] [18]
The fruitless gene (fru) is a Drosophila melanogaster gene that encodes several variants of a putative transcription factor protein.Normal fruitless function is required for proper development of several anatomical structures necessary for courtship, including motor neurons which innervate muscles needed for fly sexual behaviors.

Transformer (tra) is a family of genes which regulate sex determination in insects such as flies. [1] [2] Among its effects, it regulates differences between males and females in Drosophila fruit flies. [3] The tra-2 gene is needed for sexual differentiation in female fruit flies, and for spermatogenesis in the males.
Sex-lethal (Sxl) is a gene found in Dipteran insects, named for its mutation phenotype in Drosophila melanogaster 1] [2] It is most closely related to the ELAV/HUD subfamily of splicing factors. [3] In fruit flies, this protein participates in alternative splicing of the transformer gene, deciding the sex of the fly. [4]
Drosophila (Fruit Flies): Insects like fruit flies exhibit CASI in the differentiation of somatic tissues, where sex-specific transcription factors directly influence ...
Millions of fruit flies are being dumped over Los Angeles as officials try to fight back against an invasive species. Around 2.25 million sterile male fruit flies will be dropped over the Leimert ...
white, abbreviated w, was the first sex-linked mutation 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.
To rid your kitchen of fruit flies, the first step is to destroy their breeding ground. Fruit flies lay eggs on the surface of ripening fruit, so for the time being, move your produce into the ...
