WebApr 4, 2024 · On the synaptonemal complex of bivalents, structures called recombination nodules are formed. In an event known as crossing-over or genetic recombination, these recombination nodules promote genetic exchange amongst non-sister chromatids of the synaptonemal complex. There can be several recombination instances on each bivalent. WebMale meiosis recombination visualized by immunofluorescence of a mouse pachytene-stage nucleus spread. (A, B) The spermatocyte was immunostained with antibodies against MLH1 in order to identify the crossover sites (CO) between paired homologous chromosomes.
