In which phase does crossing over occur?
Understand the Problem
The question is asking about the specific phase in the process of cell division where crossing over occurs, which is a critical event during meiosis. Understanding the details about meiosis and its phases, particularly prophase I, will help in answering the question accurately.
Answer
prophase I of meiosis
The final answer is prophase I of meiosis.
Answer for screen readers
The final answer is prophase I of meiosis.
More Information
During prophase I of meiosis, homologous chromosomes come together to form tetrads, where they exchange genetic material at points called chiasmata, enhancing genetic diversity.
Tips
A common mistake is confusing prophase I of meiosis with similar phases in mitosis or later stages in meiosis. Remember that crossing over is specific to meiosis and occurs before the chromosomes are aligned at the metaphase plate.
