Temporal variation in shell growth rate of cockle Anadara granosa in relation with its reproductive cycle

Testicular spermatogenesis comprises a precisely timed and synchronized development of several generations of germ cells involving spermatogonial mitosis (proliferative phase); spermatocyte in which genetic material is recombined and segregated (meiotic phase); morphological transformation of the undifferentiated spermatids into highly specialized motile sperms (spermiogenic phase) [5].
