Final answer:
Turner syndrome is caused by nondisjunction which can occur in either oogenesis or spermatogenesis, resulting in a female with only one X chromosome.
Step-by-step explanation:
Turner syndrome can result from nondisjunction in option E: either meiotic division of either oogenesis or spermatogenesis. Nondisjunction is a process where chromosomes do not separate properly during cell division, and it can occur during either meiosis I or meiosis II. In meiosis I, if homologous chromosomes fail to separate, it results in gametes that either have an extra chromosome or are missing one. During meiosis II, if sister chromatids fail to separate, it can result in a similar situation. Turner syndrome is usually the result of a female having just one copy of the X chromosome, a condition known as monosomy. This can occur via nondisjunction during either oogenesis in the mother or spermatogenesis in the father.
