  1. a Infertility, Stature, Sexual Dev. Concerns regarding health and aging
  2. b escape inactivation on Xp
  3. c Paramesonephros
  4. d She has a X linked recessive disease (because she shouldn't be expressing that unless she has to abnormal Xs to choose from---it also means ALL her cells are inactivating the same X)

    can also diagnose with methylation pattern

5 True/False Questions

  1. Genetic Linkage StudyHyp. driven
    Studies gene directly
    good for mendelian/complex
    most hyp. wrong
    have to apply bonferroni correction

    can look for variations in candidate gene tagged by nearby markers between cases and controls

    Must match
    Watch out for stratification (leads to false positives)
