Summary Introduction

To determine:

The need for meiosis in spermatogenesis.

Steps involved in spermatogenesis.

Introduction:

The process of production of sperm is termed as spermatogenesis. This process occurs in seminiferous tubules and is based on three principles. First, it divides and remodels one large germ cell into four small mobile cells. Second, it divides the chromosome number to half, so that when a sperm fuses with an egg, the chromosome number of the zygote does not double up. Third, the shuffling of a gene in each chromosome results in the new genetic combinations that make a child different from his parents.
