It take place in testis

 

It take place whole life

 

In maturation phase many series of spermatogonia & residual spermatogonia are formed

 

Growth phase take place short period

 

Less growth during growth phase

 

No any division in growth phase

 

In growth phase primary spermatocyte formed

 

During maturation phase 4 spermatid formed

 

In this meiosis first then differentiation

 

sperms are motile

in ovary

 

45 to 50 years

 

Oogonia, accessory nurse cell & follicle cells are formed

 

 

long period

 

More growth during growth phsae

 

Meiosis start in growth phase up to diplotene stage

 

Primary oocyte formed

 

1 ovum and 3 polar bodies are formed

 

In this differentiation first then meiosis

 

Ova is immotile.
