9. Plants are not known to have different sexes. A. True B. False These ere are vario are various methods for sex determination in different ai include: A. Environmental conditions C. haplodiploid system B. Sex chromosomes D. All of the above 11. How could you verify that a gene you suspect to be X linked is actually located on the X chromosome? A. Set up reciprocal crosses B. Set up a two C. Set up crosses between the F1 and both parental types D. Both A and B point test cross with another gene known to be located on the X E. None of these choices are correct 12. A dosage compensation: A. An X chromosome can be inactivated B. Gene expression can be increased from a single X chromosome C. Gene expression can be reduced from a pair of X chromosomes D. All of these choices are correct E. None of these choices are correct 13. A mutation in Xist which prevents binding to proteins that promote compaction would interfere with which stage of X inactivation? A. Initiation B. Spreading C. Maintenance D. None 14. Dosage compensation is not required for all X linked genes in mammals A. True B. False 15. Which of the following does not inactivate an X chromosome? A. Mammals B. DrosophilaC. C. Elegans D. Human 16. Sex determination in humans and Drosophila is similar in the fact that A. the ratio of X chromosomes to sets of autosomes determines maleness or femaleness in both B. males in both will always have one Y chromosome, whereas females will not have a Y chromosome C. females lack X chromsomes D. males have one X chromsome and females have two X chromosomes
