  1. a,bX or Y chromosome to Autosome ratio (mapped DNA density).
  2. cExpression levels of sex-specific genes. Expression levels are FPKM (fragments per kilobase per million reads) values.
  3. dLevels of splicing events are summarized. PSI, proportion spliced in. PSI values close to 1 represent male-like splicing, and PSI values close to 0 represent female-like splicing.
  4. *D20-c2 cell line: 0.53 for X:A, 0 for Y:A ratios (no RNA-Seq result).
  5. †,‡Male or female characteristics, respectively, that are determined based on RNA-Seq analyses of 100 different fly lines (whole animals, P < 0.05, one sampled t-test).
