RESUMO
A deficiency spanning section 84B-D of the proximal right arm of chromosome 3 of Drosophila melanogaster has been utilized as a screen for mutations that aid in the genetic dissection of this developmentally interesting region.—Ninety-two mutations have been recovered, of which 12 have been localized by deficiency and complementation mapping to the 84B1,2 doublet, the site of the Antennapedia complex (ANT-C). This has permitted a more precise description of the genetic organization of this complex locus.—A collection of 31 mutations that reside in 84C1-D2 displays an intricate circular complementation pattern, characterized by two clusters of mutations that exhibit semi-lethality, negative complementation and temperature sensitivity. Mutations affecting seven additional functional groups within the 84B-D region were also recovered.
