Synapsis, also called syndesis is the process
of pairing between homologous chromosomes during meiosis. The exchange portions
of their chromatids enables pairing of homologous chromosomes prior to their
segregation and chromosomal crossover. This takes place during prophase I of
meiosis and this process is perilous for accurate segregation of the
chromosomes.
The two body systems are the muscular system and the skeletal system.
