Question

what is the result when homologous chromosomes fail to separate normally during meiosis? (1 point) independent assortment replication nondisjunction crossing - over

Explanation:

• Independent assortment: Random distribution of non - homologous chromosomes during meiosis, not related to failure of homologous chromosomes to separate.
• Replication: Process of DNA copying, not about chromosome separation in meiosis.
• Nondisjunction: Defined as the failure of homologous chromosomes (or sister chromatids) to separate properly during cell division (including meiosis), which matches the description in the question.
• Crossing - over: Exchange of genetic material between homologous chromosomes, not a failure of separation.

Answer:

C. Nondisjunction
