Yuna and Tidus.. *Spoilers*

[cally777]

You could equally ask what would happpen if Auron tried to have a child with anyone (Lulu for example). Being as he was dead.

Seymour would be another case in point. He was married to Yuna too so their baby would be legitimate ironically, tho maybe zombiefied.

Can pyreflies generate sperm?

[BG-57]

Sure. That would be a relatively minor feat compared to a giant monster or entire city filled with people.

[[.Pearl.]]

I think it would be half invisible and be chronically surrounded by pyreflies, like Bahamut's little fayth kid.

My hypothesis is that a form of meiosis and self fertilisation involving only Yuna's DNA would occur. And thus the child would most definitely be female, but would not share exactly the same genes as Yuna. This is because in some cases, a recessive allele in Yuna's DNA will pair up with another recessive allele, forming a dominant characteristic in Yuna's child's DNA. This dominant characteristic would not be present in Yuna herself because originally the allele was recessive. And thus Yuna's child would be genetically very similar to, but not exactly the same as Yuna. I hope I have clarified the situation.

dude are you the guy that sat next to me in high school biology?
i always wondered what happened to that guy...
