Individuals with Down's syndrome are not necessarily sterile; they can be fertile,although they exhibit physical and mental developmental delays.Turner's syndrome $(45, XO)$ results in sterile females with rudimentary ovaries.Klinefelter's syndrome $(47, XXY)$ results in sterile males with underdeveloped testes.Therefore,individuals with Down's syndrome are the only ones among the options who are not inherently sterile.

Which of the following disorders does not result in a sterile individual?
