Solution
option first is correct because in primary spermatocytes gives us 4 gametes while primary oocyte gives us only one functional gametes.
spermatogenesis ans oogenesis both uses process of meiosis because in each process gametes are formed which are haploid.
oogenesis happened prior to fertilization but spermatogenesis completed bfore fertilization.
oogenesis is occure from birth to menopause while spermatogenesis occure from birth to death.
