Question

what is the primary difference between spermatogenesis and oogenesis?
number of gametes produced
production of non - viable cells
presence of mitochondria
formation of specialized blood cells

Explanation:

Spermatogenesis produces four viable sperm cells from one spermatogonium. Oogenesis produces one viable egg cell (ovum) and three non - viable polar bodies from one oogonium. So the primary difference lies in the production of non - viable cells.

Answer:

production of non - viable cells
