Vedclass · Answer

(D) Meiosis is a reductional division that occurs in two stages: meiosis-$I$ and meiosis-$II$.In meiosis-$I$,the chromosome number is reduced to half. If a cell starts with $42$ chromosomes,after meiosis-$I$,each daughter cell will have $21$ chromosomes.Meiosis-$II$ is an equational division,similar to mitosis,where the chromosome number remains the same as the parent cell entering this phase.Therefore,since the cells entering meiosis-$II$ have $21$ chromosomes,the daughter cells produced at the end of meiosis-$II$ will also have $21$ chromosomes.

In the initial stage of meiosis,a cell has $42$ chromosomes. How many chromosomes are present at the end of meiosis-$II$?
