I'm no biology expert either, but there seems to be cases of parthenogenesis with usually all female offsprings but which switches to all male periodically some time of the year.
Seems like a cool way to keep the flavor of an asymmetrical gender ratio, while also tying iruxi biology to their love of astrology, since I assume predicting the arrival of male hatchlings would be a big deal in, say, a mostly female insular community. Especially if we make the cycle longer than a year, like a once-in-a-decade event.
Anyway, it sure is pretty nice to have these bits of lore sprinkled everywhere, like on an otherwise generic disease resistance feat !
