Stages during which recombination of genes occurs in meiosis are
(i) Crossing over is exchange of genes between the non-sister chromatids of homologous
chromosomes. It occurs at recombination nodules during pachytene stage of prophase-I of meiosis-I arid is regulated by recombinase enzyme.
(ii) Arrangement of-bivalents at the equator o.f the spindle duringmetaphase-I of meiosis.
