Having been in this fandom for a while, I've come across a handful of fans who believe that Inuyasha, like other famous hybrids, is sterile simply because
he is a hybrid, nothing more, end of story. While this is
a legitimate possibility, it's not an absolute. Why? Because sterile hybrids aren't so simply for being hybrids--they're sterile because of an odd chromosome count. Hybrids in which both parents have the same number of chromosomes, such as "grolar bears" (grizzly/polar bear) and "camas" (camel/llama), are, in fact, fertile.
The question then falls to how many chromosomes youkai have, which is never explained in the series (nor does it need to be). Thus, it is up to personal interpretations, theories, and opinions.
So if you, as a fan, decide that youkai should have 44 or 48 chromosomes or something and therefore hanyou would be sterile, then great! That's your opinion and you're free to have it. Personally
I prefer the idea that youkai, like humans, have 46 chromosomes so that their hanyou offspring are fertile, but hey, that's just me. Either interpretation can be supported by science and neither are disproven by canon!
I'm planning on making other parts at some point. If I ever get around to it, they'll cover things such as the "litter" theory (which I'll say upright doesn't work), hair colors, and the involvement of youki in hybrids' features.Also, before anyone starts whining about how I'm "taking this too seriously" or "looking too deep into it" or whatever...I don't care.
As a fan, I'm allowed to look into any aspect of the series as deeply or as shallowly as I please, as are you. Anatomy/biology and genetics are things I find interesting and enjoy learning about, and I like to apply my nerdknowlege to things like this because I genuinely enjoy doing so. So please take your "you're taking this too seriously" complaints somewhere else.Background texture
