WebCrossover occurs between non-sister chromatids of homologous chromosomes. The result is an exchange of genetic material between homologous chromosomes. Prometaphase I The key event in prometaphase I is the attachment of the spindle fiber microtubules to the kinetochore proteins at the centromeres. WebThe process of crossing over occurs during meiosis and involves the exchange of genetic material between homologous chromosomes. This allows for a variety of different combinations of alleles to be generated, which contributes to an increase in the genetic diversity of the children. graphic image supplies
