http://api.3m.com/significance+of+crossing+over+in+meiosis WebIn sexual reproduction, crossing over in meiosis shuffles the genes to produce genetic diversity. This is where homologous chromosomes pair up and exchange parts with another. Since homologous chromosomes can only have the same pair of genes or slightly different, the crossing provides shuffling and variation of genetic material.
