#32So those aren't a third sex, it's individuals with both male and female reproductive cells.
Like in "the player of games" the third sex was both female and male.
Is that how it was? If my memory serves the third sex was effectively "female", in that you had:
- producer of small gamete (human male)
- producer of large gamete (half of human female)
- incubator of embryo (half of human female)

#33"each sex can enter fertile pairings with 22,960 others" Imagine its Tinder profile :)
Or Twitter pronouns.

“As a user, I only want to search for users whom I can pair with. All incompatible users should be excluded by default”.
Now go and build it.

I think it depends on how you define sex, or perhaps even gender would be more accurate? In any case, I think what's being proposed is there are still on 2 unique sexes. - some of the species have one - some of the species have the other - some have the ability of both. Technically, yes, that's still only two.
How do you define sex? Because what you just described sure sounds like a third sex to me. Your description is premised on the assumption that there are only two sexes to begin with, and define the third sex in terms of the two sexes you assume to be the only ones that exist. Instead you could describe them as sexes A, B, and C where any of following pairings are valid for reproducing: A and B, A and C, B and C, or C…

Are we defining sex by the type of gametes produced by an organism?
> they can produce normal male or female colonies when they reproduce sexually with other P. starrii colonies

Tinder is not necessarily about "fertile pairings" though, but I guess humans (and some monkeys) are pretty unique in nature in that regard :)
In using Tinder at all? Yeah, that's pretty much just humans.

There is a massive difference. With that kind of mushroom one can expect that any random pair is very likely to match up. With humans you have tad less of 50% chance of being able to make kids with any random otherwise fertile human.
Err, that is an uncharitable reading of GP imo. If you pair males and females (rather than just "humans") then the anology holds quite well no?
I think the topic is getting a bit muddled here. Are we talking about couples who can't have children because one or the other is infertile/sterile, or couples who could have children with someone else but not one another?
I'm not familiar with this latter scenario. A man being sterile is nothing like this algae's situation, as it has nothing to do with "pairing," he's simply unable to produce children with anyone.
