NTA AbhyasNTA Abhyas 2020Cell Cycle and Cell Division

Crossing over is the exchange of chromosomal segment between non-sister chromatids of homologous chromosomes. It occurs during pachytene of prophase-I of meiosis, and it results in recombination of genes, producing genetic variation. It is carried out by enzyme recombinase.
