Which of the following statements is INCORRECT? Sex-limited traits affect a structure or process that is found in one sex but not in the other. Sex-influenced traits appear in both sexes. Expression of sex-influenced traits may differ between sexes because of hormonal differences. Pattern baldness is autosomal recessive in men, but autosomal dominant in women. Which of the following statements is NOT TRUE of complete androgen insensitivity syndrome (CAIS)? There is loss of function of the X-linked AR gene specifying the androgen receptor in males. Affected males cannot produce testosterone. Affected males have external genitalia that assume the default female state. Persons with CAIS are externally female but sterile because they lack the internal duct systems of either sex.
