Summary Introduction

Introduction:

Spermatogonial mother cells divide mitotically, and the primary spermatocytes divide meiotically to produce secondary spermatocytes. The meiotic division of spermatocytes makes it haploid and different from its diploid primordial mother germ cell. The haploid spermatozoa fuse with haploid ova of females to give rise to a diploid zygote.
