Notes:
In D. hydei two new mutants, In(1)f3 and IN(5)Z, show obvious mosaic gene expression. Their phenotypic expression is susceptible to the breeding temperature and to the addition of a supernumerary Y chromosome to the chromosome set. In this respect the mutants resemble standard cases of position-effect variegation based on the action of heterochromatin. However, since neither centromeric nor sex chromosomal heterochromatin apparently are involved, the mutations point to a new type of variegation provoked by euchromatic sections. The mosaic patterns of these mutants, in particular those of In(1)f3, will be described.
