Indirect effects of ploidy suggest X chromosome dose, not the X:A ratio, signals sex in Drosophila.

PLoS biology - 1 Dec 2007

Erickson James W, Quintero Jerome J

Abstract excerpt

In the textbook view, the ratio of X chromosomes to autosome sets, X:A, is the primary signal specifying sexual fate in Drosophila. An alternative idea is that X chromosome number signals sex through the direct actions of several X-encoded signal element (XSE) proteins. In this alternative, the influence of autosome dose on X chromosome counting is largely indirect. Haploids (1X;1A), which possess the male number...
