Down(s) Syndrome

Born with an Extra Chromosome.

So are they Human, or not?

>> No.2300054

Yep, they're humans. But in this case (down syndrome) with a triploid chromosome 21.

>> No.2300052

No, it's kind of obvious.

>> No.2300072

Genetically different so not human

or else chimps are human

>> No.2300086

>>2300072
chimps have different genes/chromosomes.
downs have +1 chromosome.

Can they produce viable offspring though?

>> No.2300098

In a scientific context, no. In any other context, yes.

MINDS BLOWN...

>> No.2300102

>>2300090
Yes, they can. A trisomy is not inheritable. Only the dude with a trans-local trisomy will produce similar offspring.

>> No.2300108

Lets think of other gene defects.
Like monoploid ones. They're still human.
What about deaf (due to genetics) people? Human? I think so.

>> No.2300114

>>2300108
Thats not entire chromosomes

>> No.2300127

>>2300114
Yeah, but someone with down syndrome will produce a normal offspring.
It inherits the way every other human beeing does.

what if they have both?

both genetic and Chromosome diffrences. Say a dwarf with downs?

>> No.2300166

>>2300160
inhuman.

>> No.2300168

Technically speaking, they could breed with another human and have kids that are fertile.

So yes, they are humans.

tigers can breed with lions........... diffrent dogs breed with each other all the time........

>> No.2300184

>>2300178
Pigdogs such as yourself are a product of interspecies breeding so I say no.

So any Human with a Chromosome defficiancy or acouple extra due to any reason with a diffrence in genetics when born or for any other reason is not human................

Therfore they are animals............

>> No.2300200

>>2300178

Yep, but the progeny of lion and tiger would not be fertile.

And when you breed two dogs, it makes a dog. Wow. That was an impressive counter argument.

You should read the definition of "species". I highly recommend you the works of Ernst Mayr, who gave a clear notion in 1942.
Sometimes complicated, but could make you understand your error.

Great. Just contridict yourself right there. Pigdog's?

PIGDOGS?????? Pig's and Dog's are diffrent species HERPDERP

Sorry dont know much about biolgy i was unaware.

what about wolf's and dogs?

That's a good question...

"dogs" are a sub-species of Canis lupus, which is commonly known as "wolves".
Theoretically, it may be possible to have a viable and fertile hybride. I did not study a concrete example of this kind, but it may be possible.

Well, at least, they can fuck, no problem. There is a very high probability the female makes babies. But what would be the status of these "half sub species" individuals... If they are not fertile, you can call them " bastards", but if they are fertile, you may create some special kind of new specie/sub-specie...

>> No.2300271

Yes. They can interbreed with other humans and produce fertile offspring (only a few males: females are sterile).

>> No.2300276

>>2300259
Dogs and wolves can have pups but the pups are infertile

>> No.2300289

>>2300276

thanks, i was not sure.
so that means a sub specie is "isolated" from the specie it comes from.

i find that fucking awesome. but i'm a fucking biologist, even a bacteria dividing could make me cum.
