Well, according to Wikipedia, only those who took part in a mating ritual with another female laid eggs, suggesting that the ritual itself caused them to ovulate.
According to Wikipedia: "However, ovulation is enhanced by female-female courtship and 'mating' (pseudo-copulation) rituals that resemble the behavior of closely related species that reproduce sexually."
That's pretty different from "only those who took part in a mating ritual with another female laid eggs".
May I then also quote from wikipedia
"A common theory is that this behavior stimulates ovulation, as those that do not "mate" do not lay eggs"
So yes... Only those who mate with other females lay eggs. Maybe you stopped reading after your part?
"The new research by Baumann and his team reveal that these lizards maintain genetic richness by starting the reproductive process with twice the number of chromosomes as their sexually reproducing cousins. These celibate species resulted from the hybridization of different sexual species, a process that instills the parthenogenetic lizards with a great amount of genetic diversity at the outset. And the researchers found that these species could maintain the diversity by never pairing their homologous chromosomes (as sexual species do by taking one set of chromosomes from each parent) but rather by combining their sister chromosomes instead. "Recombination between pairs of sister chromosomes maintains heterozygosity" throughout the chromosome"

As a side note, I've looked at several web-articles including national geographic, and have so far found not a single one that says these lizards require another female to reproduce. All it says is they often engage in a mating ritual (which hasn't actually been fully classified as sexual activity as far as I've seen.. Not that it matters, but just for posterity's sake) to help stimulate ovulation, where one will lay on top of another and they will both lay eggs. Whether this is the equivalent of them having sex, or whether it's simply them giving birth together seems somewhat unclear.

It also doesn't say they are incapable or don't reproduce on their own-- on the contrary they are labelled an asexual species-- anywhere except Wikipedia so far, just that they seem to be more likely to reproduce when there is another lizard around
Finally, considering these lizards are the result of mixed breeding between the females of one species and the males of another, it's quite likely they'd also be inclined to engage in mating activity with other species, not just females of their own kind
Why don't we just put a few individuals in separate boxes and then a group in another box? That seems simple enough. <_< I guess after you'd have to wonder about contact... perhaps a lizard doll with pheromones?
@rosalinas Learn sience, not lgbt speeches. Animals don't know about homosexuality. This is substitution of concepts.
"Homosexual: in animals, this has been used to refer to same-sex behavior that is not sexual in character (e.g. ‘homosexual tandem running’ in termites), same-sex courtship or copulatory behavior occurring over a short period of time (e.g. ‘homosexual mounting’ in cockroaches and rams) or long-term pair bonds between same-sex partners that might involve any combination of courting, copulating, parenting and affectional behaviors (e.g. ‘homosexual pair bonds’ in gulls). In humans, the term is used to describe individual sexual behaviors as well as long-term relationships, but in some usages connotes a gay or lesbian social identity. Scientific writing would benefit from reserving this anthropomorphic term for humans and not using it to describe behavior in other animalsss, because of its deeply rooted context in human society".

@guest And at one time we thought animals had zero concept of "self" and that they didn't have "language". We were obviously wrong on both accounts. A dolphin trying to rape a human knows exactly what it's doing.
Nobody ever takes this argument serial. The gay lizard argument is nothing like the gay frog argument.
In all seriousness, anytime I point this out... or the penguins... or the seals or whales or beetles.... or.. monkeys.. on nearly any other site, it doesn't end very well.
Sorry bout facts for them.
Anyway, this isn't the only species.
