    I'm just wondering that during crossing over, is there only one point of crossing or is there more?

    there are many different lengths of DNA that gets exchanged at different points. One exchange point = chiasma, multiple = chiasmata

    It is possible that chrosome pairs are crossing twice. But as a rule it is one. If it is one two chromatids are crossing each other most of the time. If it is tiwce both chromatids and telomere perform crossing over.
