Vedclass · Answer

(D) In the process of frog oogenesis,the primary oocyte undergoes the first meiotic division (meiosis-$I$).During this division,the diploid $(2n)$ primary oocyte divides into two unequal haploid $(n)$ daughter cells: a large secondary oocyte and a small first polar body.Therefore,the reduction of the chromosome number from diploid to haploid occurs when the first polar body is separated.

In frogs,the chromosome number is reduced to half during which of the following stages?
