Gametogenesis, shown in fig 2.5, is the process by which a diploid cell becomes haploid (Severson, von Dassow and Bowerman, 2016). This is achieved by meiosis I and meiosis II, which are 2 sequences of cell proliferation (Severson, von Dassow and Bowerman, 2016). 75% of the chromosome copies are removed by careful separation (Severson, von Dassow and Bowerman, 2016). The re-making of the nucleus characterises the differentiation of gametes in males (Severson, von Dassow and Bowerman, 2016). There is very little known about this process in comparison to mitotic spindle operation according to: (Severson, von Dassow and Bowerman, 2016).
