What are the mechanisms underlying this phenomena?

I have a few questions regarding these articles over here. First and foremost, allow me to share the articles with you so that you are aware what I am referring to.

"Honey bee has two fathers, and no mother": https://zoologicallyobsessed.tumblr.com/post/180617284154/a-honeybee-with-two-fathers-and-no-mother

They claim that two male honey bees created a zygote, that two sperms "fused" and created a zygote.

> Genetic analysis revealed that nine of the 11 gynandromorphs had either two or three fathers. Astonishingly, one gynandromorph -- the seemingly normal female control -- actually had two fathers and no mother -- an event that could only have resulted from sperm fusion.

> “The female bee that had two fathers created by the fusion of two sperms is the first reported in haplodiploids and is an interesting phenomena considering that attempts to fuse two sperm in mammalians have not [been] found to be possible,” Ms. Aamidor elaborated in email.

> This study begins to expand our limited understanding of the truly unusual ways that sexual animals can fuse their genomes.

This other one is the actual paper described in Forbes: https://royalsocietypublishing.org/doi/10.1098/rsbl.2018.0670

> Bee K was female and diploid throughout, but lacked any maternal nuclear genetic material. We propose that K was created by a fusion of two sperm nuclei, resulting in an androgenic diploid bee. This is the first report of an individual created by the fusion of two sperm in any Hymenopteran. K was able to develop to the adult stage, showing that a bi-paternal bee is viable ... The viability of K suggests that there are no impediments to the development of a bi-paternal female honeybee, as has previously been shown for bi-maternal

My questions are, was it really two "sperm" or two "eggs" fusing or was it something else? In one bee, these people claimed "there were no maternal genes, so it must have been two males creating it", while in the other bee, these people claimed that "there were no paternal genes, so it must have been two females creating it",

But there could be other reasons as to why one bee "had no maternal genes", while the other bee "had no paternal genes", right? What other reasons could it be?

They simply "propose" it's this way, and never observed it occur. They assume it, which means their "two sperm or two eggs fused to create a zygote" is unsubstantiated.

It could be something else, right? But what else would result in "a bee without maternal genes" and "a bee without paternal genes", other than "two males creating it" and "two females creating it", respectively?

The actual article highlights that it's androgenesis that resulted in "a bee without maternal genes" and gynogenesis that resulted in "a bee without paternal genes".

Is that it? Were androgenesis and gynogenesis the reasons there were so-called "bees with two fathers and no mother" and "bees with two mothers and no father"?

They claim zygotes "created" from androgenesis "have no mother", and from gynogenesis "have no father".

Don't see how that is the case given in androgenesis egg is still used, and in gynogenesis sperm is still used meaning the zygotes do have a "mother" and a "father" respectively.

It's just that the egg and sperm become deactivated and do not "contribute genetic material", respectively. Doesn't mean they are not necessary in the "reproduction" and play no role, right? It's not as if a male "creates" a zygote on its own in androgenesis, without a female, and it's not as if a female "creates" a zygote on its own in gynogenesis, without a male, right?

It's false to claim the female plays no role in the "creation" of zygote in androgenesis, and the male plays no role in the "creation" of zygote in gynogenesis, right?

Which means the zygotes do have a "mother" in androgenesis, and a "father" in gynogenesis, and it's false to claim the bee from androgenesis "has two fathers and no mother" when they do have a "mother" and the bee from gynogenesis "has two mothers and no father" when they do have a "father", right?

To claim the zygote from androgenesis has no "mother", erases the role of the egg. The two sperm in the bee I mentioned above couldn't have formed a zygote on their own, and had to use an egg in the process of androgenesis, therefore the zygote does have a "mother", albeit a "mother" whose genetic material was deactivated by sperm, right?

To claim the zygote from gynogenesis has no "father", erases the role of the sperm. The two eggs in the bee I mentioned above couldn't have formed a zygote on their own, and had to use a sperm in the process of gynogenesis, therefore the zygote does have a "father", albeit a "father" whose genetic material was deactivated by egg, right?

Last but not least, does fertilization occur during androgenesis and gynogenesis? Or do sperm and egg use each other without fertilization? If the latter, please explain how ...
