This is very interesting to me. Do organisms that are tetraploid, and more, have a third sex, a third gamete, or are they always sterile?

Triploid are always sterile or asexual. They lack different sex-determining genes. The one example of a tetraploid animal I found (Australian burrowing toad) still only has two sexes, so I’m not 100% sure how that works.
