The synthesis of compound autosomes in the Australian sheep blowfly Lucilia cuprina.

The synthesis of the first compound chromosome strain in Lucilla cuprina (Diptera: Calliphoridae) (Weidemann) is described. Crosses between the compound chromosome strain and a chromosomally normal strain produce no offspring, whereas crosses between compound chromosome-bearing individuals are fertile. Cytological evidence is presented that compound chromosome arms assort art random with respect to one another during spermatogenesis.
