It looks like there are cases where the size of the gametes are identical. But when this happens they don’t refer the organism’s sex as “male/female” and instead use “+/-“. https://en.m.wikipedia.org/wiki/Isogamy https://en.m.wikipedia.org/wiki/Isogamy
Going a step further I found this:
>Depending on the group, different mating types are often referred to by numbers, letters, or simply "+" and "−" instead of "male" and "female", which refer to "sexes" or differences in size between gametes.

So it does seem to be a strict definition and anything outside of the strict definition is given an alternate identification scheme.
- rsynnott 4y agoHere's a fun edge case: https://en.wikipedia.org/wiki/Indotyphlops_braminus#Reproduction https://en.wikipedia.org/wiki/Indotyphlops_braminus#Reproduc... All individuals of this snake are female (presumably 'female' here is defined relative to other snakes) and reproduce parthenogenetically (sic?). By your definition, these wouldn't have a sex at all, presumably.
- yencabulator 4y agoA closely-related species using the same or similar chromosomes, where male/female exist, is likely where it came to be that the observed individuals of these snakes have all been determined "female", even if no "male" has been observed.
