(i) Synapsis
During meiosis-I, the process of the pairing of two
homologous chromosomes are identified as synapsis. It is so
exact that pairing is not only between corresponding
chromosomes but within the corresponding individual
units.
(ii) Bivalent
The complex created by a pair of synapsed
homologous chromosomes are termed a bivalent or a tetrad.
It contains four chromatids.
(iii)Chiasmata The chiasmata formation is the implication of
completion of crossing over and starting of the separation
of chromosomes. The chiasmata are produced when the
chromosomal parts begin to oppose each other except in
the region where these are in touch. Thus, chiasmata
the formation is essential for the detachment of homologous
chromosomes.
