Meiosis and Life Cycles - 8 Crossing Over After crossing over takes place, the still-joined homologues pull apart slightly, although the chromosomes are still attached at the chiasmata. All things that we normally think of taking place in a prophase also occur in prophase I of meiosis, including attaching spindle fibers to each chromosome of the attached homologous pairs. Early Prophase I

Unformatted text preview: Synapsed Homologous Pairs Metaphase I Metaphase I Synapsed homologous pairs of chromosomes are moved to the equator by the spindle complex. The alignment is random; some maternal chromosomes will orient facing one pole along the equator; others face the opposite pole. The random alignment of homologous pairs of chromosomes at metaphase increases genetic variation....
