hen the replicated chromosomes fail to separate during meiosis, this process is knownas _____. aNondisjunction bDisjunction cReplication dMutation

Break Down the Problem

1. Identify what happens when replicated chromosomes fail to separate during meiosis.
2. Determine the term that best describes this phenomenon from the given options.

Relevant Concepts

• Nondisjunction: This term refers specifically to the failure of chromosomes to separate properly during cell division, which can occur in meiosis or mitosis.
• Disjunction: This is the normal separation of chromosomes during cell division.
• Replication: This refers to the process of copying DNA.
• Mutation: This refers to a change in the DNA sequence, which is not directly related to chromosome separation.

Analysis and Detail

The question pertains to a specific event that occurs during meiosis when homologous chromosomes or sister chromatids fail to separate. In this case, the correct answer must precisely reflect the failure to separate which leads to an abnormal number of chromosomes in the daughter cells.

Verify and Summarize

By analyzing the definitions of the terms involved, it is clear that nondisjunction is the only term that accurately describes the failure of chromosome separation during meiosis.

Final Answer

The correct answer is a) Nondisjunction.
