Synaptonemal complex is formed in which of the following substages of meiosis-1?

✅Explanation:
-The synaptonemal complex is formed during the zygotene stage of prophase I in meiosis I. During zygotene, the homologous chromosomes pair up and form a structure called the synaptonemal complex. The synaptonemal complex is a protein structure that holds the homologous chromosomes together and allows for the exchange of genetic material between the chromosomes.
