It gets really weird with lizards.
Two species of lizard, can hybridize (like horse+donkey = mule) to create a parthenogenetic hybrid.
These are the relatively well-known "lesbian lizards", such as the New Mexico Whiptail.
>they hump each other to stimulate production of eggs, producing half-clones with some diversity by shuffling their own genes around (not each other's)
It seems like this is pretty common among whiptails, there are multiple such lineages.
Some of these hybrids are triploid - they have three sets of chromosomes.

According to some papers, these triploids occur when diploid unisex lizards hybridize *again* with (male lizards of?) other species.

>Triploid unisexual vertebrates are thought to arise through hybridization between individuals of a diploid unisexual lineage and a sexual species, although additional evidence that confirms this mechanism is needed in numerous groups.
Another paper restates this theory, and provides evidence for it.

In the lab, they created tetraploid - four chromosome - lizards by fertilizing some (wild origin?) triploids with male lizards.
Supposedly these are stable at least to the third generation of parthenogenesis.
>The tetraploid females have established self-perpetuating clonal lineages which are now in the third generation.
