Do any species have more than 2 sexes?
But nature does have multiple examples of more than two “mating types” within a species; clam shrimp have a male as well as two varieties of hermaphrodite, which either self-fertilize or mate with males but cannot mate with each other. The stark male/female split in many organisms has long puzzled biologists.
Are there 3 sexes?

How many types of sexes are there?
The four genders are masculine, feminine, neuter and common.
How many biological sexes are there?
We know, without question, that humans are not just born male and female. There are at least six biological sexes that can result in fairly normal lifespans.
What is an advantage of having only 2 sexes?
Those species that exhibit sexual reproduction have an evolutionary advantage over “cloners” in that there is more diversity in their offspring. This diversity allows the species to adapt more quickly to a changing environment, or to increase its chance of survival in the existing one.
What creature has the most sexes?
One species of fungi, Schizophyllum commune, really shines when it comes to gender diversity. The white, fan-shaped mushroom has more than 23,000 different sexual identities, a result of widespread differentiation in the genetic locations that govern its sexual behavior.
Can intersex people reproduce?
Intersex people can—and do—have children. The reproduction basics need to be possible for this to occur, which typically includes the ability to have vaginal intercourse that results in implantation within a healthy womb.

Why did the two sexes evolve?
Sex evolved as an extremely efficient mechanism for producing variation, and this had the major advantage of enabling organisms to adapt to changing environments. Sex did, however, come with a cost. The evolution of sex contains two related yet distinct themes: its origin and its maintenance.
