Multiple Choice 2 points During which stage of meiosis does crossing-over occur? anaphase l of meiosis II telophase I of meiosis I prophase II of meiosis II prophase I of meiosis I

The correct answer is: prophase I of meiosis I.<br /><br />During prophase I of meiosis I, homologous chromosomes pair up and exchange genetic material through a process called crossing-over. This process results in the formation of recombinant chromosomes, which have a mix of genetic material from both homologous chromosomes. Crossing-over increases genetic diversity by creating new combinations of alleles.
