TestHub · Accepted Answer

Synapsis is the pairing of the homologous chromosome, which occurs during zygotene. The centromere split and sister chromatids move to opposite pole during anaphase II. Recombinase enzyme carries out recombination or crossing over during pachytene of prophase I. Centromere does not split during anaphase I and disjunction of chromosomal pair occurs.
