Vedclass · Answer

(A) In $Meiosis-I$,the homologous chromosomes pair up during Prophase $I$ (synapsis) and align at the equatorial plate during Metaphase $I$.During Anaphase $I$,the homologous chromosomes separate,while the sister chromatids remain associated at their centromeres.Option $A$ correctly describes this event.Option $B$ is incorrect because pairing (synapsis) occurs in Prophase $I$,not Metaphase $I$.Option $C$ is incorrect because Interphase is the preparatory phase for division,not the stage where nuclear envelopes enclose haploid sets (this occurs in Telophase $II$).Option $D$ is incorrect because Prophase $I$ involves crossing over and synapsis,not the separation of non-homologous chromosomes.

Which one of the following pairs is correctly matched?
