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 (ovum) and three non - viable polar bodies from one oogonium. The key difference is the number of gametes produced (spermatogenesis: multiple, oogenesis: one) and the production of non - viable cells (oogenesis has polar bodies, spermatogenesis does not).

Answer:

number of gametes produced, production of non - viable cells
