Yes. Kes was artificially put into it and made a point of saying it happens only once.
As to them having a tendency to single births, I don’t remember. There do seem to be few enough of them to indicate a population in decline, but…
If each couple can only have one child ever, their population would halve every generation, wouldn’t it? That’s… Isn’t that wildly unsustainable, biologically?
I suppose they could represent an evolutionary dead-end…
That’s only if you assume male-to-female ratio of 1:1 if they had, say, 10 women for each man, they would only lose 10% of their population per generation. However, if roughly one in ten pregnancies were with twins, the population would be stable.

With the known population, they wouldn’t even last a century.
