Chromosomes begin to condense.", "Image ImageDescription": "In synapsis, homologous chromosomes loosely pair up, aligned gene by gene. In crossing over, nonsister chromatids exchange DNA segments. Each pair of chromosomes forms a tetrad, a group of four chromatids. Each tetrad usually has one or more chiasmata, X- shaped regions where crossing over occurred.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
