Vedclass · Answer

(A) During meiosis,homologous chromosomes pair up to form bivalents (or tetrads) during prophase $I$. These bivalent chromosomes then align themselves at the equatorial plate (metaphase plate) during metaphase $I$. This alignment is a characteristic feature of metaphase $I$,where spindle fibers from opposite poles attach to the kinetochores of homologous chromosomes.
