Which of the following statements about sex determination in Drosophila is false?     Males transcribe sex-lethal, females do not.     The X/A ratio controls the transcription of sex-lethal.     Double-sex RNA is spliced differently in males and females.     Transformer regulates the splicing of double-sex RNA.     Functional transformer protein is only produced in females.
