Vedclass · Answer

(B) In meiosis-$I$,homologous chromosomes pair up to form bivalents (or tetrads).For a plant with a diploid number $2n = 50$,the number of chromosomes is $50$.These $50$ chromosomes form $25$ bivalents during prophase-$I$.At the equatorial plate during metaphase-$I$,these $25$ bivalents align.Each bivalent acts as a single group or unit at the equatorial plate.Therefore,the number of chromosome groups at the equatorial plate is $25$.

The number of chromosome groups at the equatorial plate in metaphase-$I$ of meiosis in a plant with $2n = 50$ shall be:
