Synapsis happen after the chromosomal DNA has simulated. The 4 chromatids are involved in crossing over of a homologous pair of chromosomes. In addition, a chromatid is a strand of a double stranded chromosome. The law of segregation states that allele pairs dispersed yet gamete development and casually unite at insemination.
