Explain why males are more vulnerable to certain genetic disorders than females.
What will be an ideal response?
Ans: By comparison, the X chromosome contains 800 to 900 genes. In addition, only some of the genes on the Y chromosome are active. Thus, when an X chromosome pairs with a Y chromosome to create a boy, some of the X chromosome’s active genes will not find a partner on the Y chromosome. These genes will be expressed whether they are normally recessive or dominant. The outcome is increased vulnerability in boys to the effects of recessive genes on the X chromosome that cause such problems as red-green color blindness, hemophilia, and Duchenne muscular dystrophy.

Jones’s emphasis on procedures corresponds strongly to the recommendations of Harry and Rosemary Wong. 4. Jones would argue that the helpless handraisers in a class are less intellectually capable than their peers. 5. Carefully managing transitions is a recommendation made by both Jones and Kounin.
