Crossing over in meiosis involves the exchange of alleles between adjacent chromatids within a bivalent, forming chiasmata and new allele combinations.
Il crossing-over nella meiosi comporta lo scambio di alleli tra cromatidi adiacenti all'interno di un bivalente, formando chiasmata e nuove combinazioni alleliche.
