^Yes but if you do the math it doesn't seem likely that 3% of the population would be able to be moved around enough to procreate with every couple and have any population growth worth speaking of.
Now something like 33% might work, one cogenitor for every married couple. But 3% doesn't seem feasible.
I agree.
And I just remembered something else from the episode. The wife gripes about how long it took to get the cogenitor, but the husband told Trip that the 3% of the population that are cogenitors was just about right.
The low cogenitor population would explain why they are not allowed to have fulfilling lives. All of their time would have to be devoted to reproduction. My impression was that having a cogenitor assigned to the couple serving aboard the starship would have to have been pretty rare.
I really wish they had revisted the Vissians -- maybe have Archer decide to try to smooth over the disastrous first contact.
A few questions that I wish had been answered:
-- I wonder whether the imbalance in the population was a result of natural selection, a disaster or genetic engineering in a bid to control population growth?
-- Or was it perhaps the consequence of many couples electing to abort cogenitors in hopes of getting a child who would have a better future? Is it even legal to abort a cogenitor?
-- How many children can a Vissian couple have? Is it likely that cogenitors -- as rare as they are -- would be made available to a couple who already has a child?
-- Is it illegal to teach a cogenitor to read? Why are they not given names?
-- Have the prejudices we witnessed in the episode always been part of the social structure of Vissia?
I think some of these questions could have been answered if the writers hadn't used up so much time on the Malcolm Eats Cheese and Gets Laid subplot (tho' it might have created an interesting conflict with Trip if the Vissian tactical officer had "borrowed" the cogenitor for a menage a trois with Malcolm -- and when he tells Trip about it, Trip berates him because he knows the cogenitor was not free to decline).
