<h3>Answer is: Scientific <em>Experiment</em></h3>
Crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
<h3>WHAT IS MEIOSIS?</h3>
Meiosis is the process whereby a single cell produces four daughter cells that are genetically different from one another.
Meiosis is able to ensure genetic diversity in the daughter cells due to a process called Crossing over.
Crossing over is the exchange of genetic material between the non-sister chromatids of homologous chromosomes. It occurs in the prophase I stage of meiosis.
Therefore, crossing over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs in the prophase I stage of meiosis.
