也許皇帝留下來的SM產生程序只有男性能通過, 女性有排斥在某ㄧ步
總之, GW在設定明確的說女性與基因種子有相斥. 這是目前的40k科技現況
First and foremost, a potential recruit must be male, as the gene-seed and zygote are synchronized only to male hormones. The three following requirements also apply:
* Recruits must be adolescents or very young adults, as the implants must be able to coordinate with natural growth hormones to stimulate the various unique physiological features of a Space Marine. In specific terms, the recruit must be about 10-16 Earth standard years of age.
* Much like a blood transfusion, there must be genetic compatibility between the recruit and the implants; otherwise organ failure may result, causing the recruit to die or simply degenerate into a state of madness.
* The mental state of a potential Marine must also be susceptible to the various training and psycho-conditioning regimes of the Chapter, and cannot be tainted by the Ruinous Powers of Chaos.
Nineteen genetically-engineered organs grown from the Chapter's gene-seed are implanted in a Neophyte to further bolster his combat and survival ability should he live to become a Brother-Marine.
