Vedclass · Answer

(C) In human somatic cells,the diploid number of chromosomes is $2n = 46$.During Mitotic Metaphase,the chromosomes align at the equator,and the number remains $46$.During Metaphase-$I$ of meiosis,homologous pairs align at the equator,but the total number of chromosomes in the cell is still $46$ (diploid).During Metaphase-$II$ of meiosis,the cell has already undergone meiosis-$I$ (reduction division),so each daughter cell contains only $n = 23$ chromosomes.Therefore,the sequence is $46, 46, 23$.

What is the number of chromosomes in human cells during the following phases: Metaphase,Metaphase-$I$,and Metaphase-$II$,respectively?
