Backtracking to earlier in the thread to Andorians (sorry), exactly how do they reproduce ?
I am not trying for titilation here - just the biology. If there are two male(ish) and two female(ish) sexes, how does the (4 lots of ?) genetic information get passed on, fertilisation occur and the foetus grow, and where ?
From what I vaguely recall, the shen
creates the initial gamete, a quarter of the necessary genetic material. The thaan
both fertilize the shen
, adding their quarters. Then the shen
passes the fertilized gamete on to the zhen
, who adds the last quarter and carries the fetus to term.
Which does tend to adhere to what I was complaining about earlier - to wit, boy-girl action fine, girl-girl action fine, but boy-boy action a no-no. And yes, I realise I'm reading too much into it.
(Aside: Memory Beta is inconsistent - it states that all four gametes are necessary to conceive, but that the zhen
contributes no genetic material to the fetus. It can't be both.)
