Genetic analysis of hook, a gene required for endocytic trafficking in drosophila.

abstract：:The behaviour of two "meiotic drive" systems, Segregation-Distorter (SD) and the sex chromosome sc(4)sc(8) has been examined in the same meiocyte. It has been found that the two systems interact in a specific way. When the distorting effects of SD and sc(4)sc(8) are against each other, there is no detectable interacti...

By employing primary trisomics we have unequivocally placed the Ep(1) gene on chromosome 6, closely linked to the Y(1) locus. Additionally we describe new alleles at ...
