10.1.3 CROSSING OVER Outline the process of crossing over in : Meiosis 1: • Prophase I - homologous chromosomes are paired up tightly into tetrads‚ then crossing over‚ the exchange of genetic material between the DNA in these tetrads occurs‚ forming a chiasmata‚ an x-shaped structure. • Metaphase I - paired chromosomes line up along the equator of a cell‚ the metaphase plate as the spindle microtubulue apparatus pulls them. • Anaphase I - The spindle microtubules pull homologous chromosomes
