Final answer:
Nondisjunction leads to chromosomal abnormalities due to improper chromosome separation during meiosis.
Explanation:
The primary outcome of nondisjunction is chromosomal abnormalities. Nondisjunction occurs when homologous chromosome pairs or sister chromatids fail to separate properly during meiosis, leading to disorders in chromosome number such as duplications or losses. This can result in genetic disorders if the affected gametes are fertilized and form zygotes.
