crossing over take place in meiosis? Anaphase I. Metaphase I. Prophase I.
Crossing over begins early in prophase I of meiosis. At the time, homologous
chromosomes Are paired along their lengths.
You will notice that, in our diagrammatic representations of crossing-over in this
chapter, we have shown crossovers taking place at the four-chromatid stage of
meiosis. ... to decide whether crossing-over occurs at the two-strand (two-
