[FMA/ FMA brotherhood] Would human chimeras pass down their chimeric traits to offspring ? can they even still have offspring with regular humans ? what about children between two different chimera types ?

I would say even human chimeras are incompatible for mating with regular humans, because they are now a different species. Even if they started human, their DNA is now mixed with animals and no longer able to impregnate a human/vice versa. 

As for offspring between chimeras, as long as they were of similar builds( a dog/man chimera could probably breed with a dog/woman chimera, but not with a bird/woman chimera).
