50 secondary spermatocytes and 50 secondary oocytes will give rise to

Explanation

Each secondary spermatocyte gives rise to 2 sperm and each secondary oocyte gives rise to 1 ova and 1 polar body. The polar body is ruptured and is used as a source of nutrition, so only one ova is produced by 1 secondary oocyte. In short, each secondary spermatocyte will produce 2 sperms so 50 secondary spermatocytes will produce 100 sperms (2*50). At the same time, each secondary oocyte will give only one Ova so 50 secondary oocytes = 50 ova.
