Question

which statement accurately describes the final phase of meiosis as diagrammed to the right? the final phase of meiosis indicates a deletion. the final phase of meiosis indicates crossing over. the final phase of meiosis indicates non-disjunction. the final phase of meiosis indicates a point mutation.

Explanation:

1. Analyze each option:

• Deletion: Involves loss of chromosomal segment, not shown here.
• Crossing over: Occurs in prophase I, involves exchange between homologous chromosomes, not final phase.
• Non - disjunction: Failure of chromosomes to separate properly during cell division. The diagram likely shows improper separation in final meiotic phase.
• Point mutation: Change in a single nucleotide, not related to chromosome separation in meiosis.

1. Conclusion: The final phase of meiosis in the diagram shows non - disjunction as chromosomes don't separate as they should.

Answer:

The final phase of meiosis indicates non - disjunction. (The option "The final phase of meiosis indicates non - disjunction.")
