Cover image (A) Monogenic reproduction is reported in three families of Diptera: dark-winged fungus gnats (Sciaridae), gall midges (Cecidomyiidae), and blowflies (Calliphoridae).(B) Sex determination via postzygotic chromosome elimination in fungus gnats and gall midges. The mechanism of sex determination is similar in the two families, with the subtle distinction that zygotes in fungus gnats are triploid because sperm provide two X chromosomes. One extra chromosome is eliminated from embryos as a result.
