Are the Saiyans doomed to extinction?

[Mr. Piccolo]

Are the Saiyans eventually doomed to practical extinction via dilution with human blood? Seeing as we only have two lines (that of Goku and Vegeta) and assuming their descendants intermarry with humans, will the Saiyan race eventually just become a thing of the past? After Goku and Vegata die, there will no longer be any full-blooded Saiyans left, so what of their descendants?

If you take a look at Dragon Ball Online, its said that nearly every human is half Saiyan or something along those lines. Eventually the full blooded Saiyans will die out, but Saiyan halfbreeds arent going anywhere anytime soon.

Full-blood saiyans are doomed, but Saiyan genes will live on in the Earthlings, possibly forever.

But wait, that makes no sense. The only way to get a half Saiyan is to either breed a Saiyan with a human or breed two half-Saiyans together. Unless you go for a bunch of incest they would be diluted to small fractions soon.

Errr... not really. Only the humans you play as have Saiyan blood, and they are not supposed to be a big part of the human population on Earth. And the amount of Saiyan blood in them is so small, they need the Dragon Balls to unlock the ability to go Super Saiyan.

[Chuquita]

On Earth, yes. There's always the possibility that in-universe Planet Saiya still exists somewhere if the "Planet Vegeta is Space Australia" theory holds, in which case as long as Planet Saiya's got a big and varied population of saiyajin (even if their culture is wildly different from Planet Vegeta's) they'd still survive.

No where is it said that nearly every human has Saiyan genes, just that their blood has spread into the Earthling population. We don't know how many that totals to. It may not even be over a 100.

They should of had a couple of long lost female Saiyans show up with the goal to keep the Saiyan race going.

Saiyan chick shows up near Capsule corp in full head to toe armor

Saiyan lady: I'm here for you Vegeta!
Vegeta: you dare challenge the prince of all Saiyans *turns Super Saiyan charges her*
Saiyan lady: *strips*
Vegeta: What!? *nose bleed, falls from the sky and crashes through some buildings*

I wonder how faithful Vegeta would be if a female Saiyan showed up...

Or maybe have a Fifi La Fume thing going on with Goku. (shes the female version of Pepé Le Pew). Actually wait a minute, how faithful is Goku?

[CaptainKatsura]

Goku is bordering on asexual. He has an intercourse if you promise him food.

[Marco Polo]

Don't forget the half-Saiyans Tarble and Gure eventually have (or already have!).

[CaptainKatsura]

Don't count as half-humans half-Saiyans, clearly.

[Marco Polo]

Yes but that's another legacy of the Saiyans.

[CaptainKatsura]

Called Freaky Alien Genotype Half-Saiyans?

[Marco Polo]

Called Freaky Alien Genotype Half-Saiyans?

They would be very freaky that's for sure

[FoolsGil]

With only 2 full blooded Saiyans, their blood with dilute with the humans until after 5 to 7 generations there will be no point in saying someone has any Saiyan in them. So yeah, the Saiyans are doomed to extinction.

[supersaiyan3]

I'm not sure it would dilute. These are two different species, so it could be possible that the Saiyan genes are dominant to human genes. If Goku and Vegeta had a sufficient amount of genetic diversity, then some (if not most) of the Saiyan traits would be incorporated into the human gene pool.

[SingleFringe&Sparks]

I think the Saiyan super strength will carry on in the humans but the SSJ potential will be bred out.

[soulnova]

Saiyan genes will stay on whatever descendants they might have... although, they might be "dormant". We can still trace some Neanderthal genes on today's population.

Goku is bordering on asexual. He has an intercourse if you promise him food.

And I would go as far as to say *any* kind of intercourse for that matter.

"What? You sure? That's strange" *stomach growls* "OH WELL"

[khalildh]

The fact that Humans and Saiyans can interbreed likely means that in their past they likely shared some common ancestor. Just like modern Homo sapiens that likely interbred with Homo neanderthalensis it is unnecessary to try and create a distinction between the human and saiyan species. The Tarble child does create some problems for a such a theory though, so it is likely that Akira Toriyama and/or the people who wrote the JSAT special likely don't care for this theory and also likely don't understand why it is unlikely that unrelated alien species would be able to procreate together.

To answer the OP's question though. The genetic material of the Saiyans will likely live on, but just as all living things do they will likely change shape into something that is likely to not appear to have many Saiyan traits.

Well they're both primates that's for sure.

Incidentally, King Kai has a pet monkey...
