In humans, the number of ova and sperms that would be produced from 100 secondary oocytes and 100 secondary spermatocytes during gametogenesis is

The correct option is 100 ova, 200 sperms.

To understand why this is correct, let's break down the processes of oogenesis (formation of ova) and spermatogenesis (formation of sperms) in humans step-by-step:

1. Oogenesis (Production of Ova):
During oogenesis, a primary oocyte undergoes the first meiotic division (Meiosis I) to produce one haploid secondary oocyte and one tiny first polar body.
When the secondary oocyte undergoes the second meiotic division (Meiosis II), it divides unequally to produce one functional ovum and another second polar body.
Therefore, each secondary oocyte gives rise to exactly one ovum.
Using this relationship:
$100\text{secondary oocytes}\times 1\text{ovum/secondary oocyte}=100\text{ova}$

2. Spermatogenesis (Production of Sperms):
During spermatogenesis, a primary spermatocyte undergoes Meiosis I to produce two haploid secondary spermatocytes.
Each of these secondary spermatocytes then undergoes Meiosis II to produce two spermatids, which subsequently mature into two functional sperms (spermatozoa).
Therefore, each secondary spermatocyte gives rise to exactly two sperms.
Using this relationship:
$100\text{secondary spermatocytes}\times 2\text{sperms/secondary spermatocyte}=200\text{sperms}$

Combining both results, 100 secondary oocytes and 100 secondary spermatocytes will yield a total of 100 ova and 200 sperms respectively.
