Allelic Negative Complementation in the Notch Locus of Drosophila Melanogaster at the Morphological Level

  • Chapter
Advances in Genetics, Development, and Evolution of Drosophila

Abstract

The Abruptex (Ax, 1–3.0) alleles of the Notch locus of Drosophila melanogaster exhibit an interesting type of allelic interaction, namely negative complementation. Heterozygous combinations of certain viable alleles are lethal or semilethal. In such allele pairs, one is always a suppressor of the expression of Notch mutants, while the other is either an enchancer of Notch or has a neutral effect on Notch (Foster, 1975; Portin, 1975).
