Turkeys can. There are probably a few other birds too,
Interesting.

I don't see why. Heterozygosity is well represented among squamates and birds too, and it doesn't stop them from being parthenogenic.
Yes, but it's the females who are heterozygous in those groups, no? Or is the matter (need I eve ask?) more complicated than that?
