Interaction of non-allelic loci in expression of the extra-sexcomb phenotype inDrosophila melanogaster

  • Aloha Hannah-Alava
Article

Summary

The expression of the extra-sexcomb phenotype is enhanced in males that are doubly heterozygous for mutants from two non-allelic loci,‘extra-sexcomb’ (Polycomb, Extra-sexcomb) and‘bithorax’ (bithorax, bithoraxoid, Ultrabithorax) as compared to the expression of the ‘extra-sexcomb’ mutants when no ‘bithorax’ mutants are present in the genotype. If the ‘bithorax’ mutants are recessive, the expression is usually greater when the non-allelic mutants are cis-hererozygotes than when they are trans-heterozygotes, but there is no difference between cis-and trans-heterozygotes in ‘extra-sexcomb’ andUltrabithorax compounds.
