THE GENETIC IDENTIFICATION OF A HETEROCHROMATIC SEGMENT ON THE X CHROMOSOME OF DROSOPHILA MELANOGASTER

[摘要] An autosomal euchromatic maternal-effect mutant, abo (= abnormal oocyte), interacts with, or regulates the activity of, the heterochromatin of the sex chromosomes of Drosophila melanogaster . It is shown that this interaction or regulation with the X chromosome involves a specific heterochromatic locus or small region that maps to the distal penultimate one-eighth of the basal X -chromosome heterochromatic segment.
