Does it count if their offspring are mules? Some species can breed, but THOSE offspring are generally sterile and cannot reroduce, and are called mules.
- Donkey + horse = Mule (hence the name)
- Muscovy duck + Mallard duck = Mulard .. and so on.
I'm not sure if mixed kids are mules at all, but there is some evidence, there are issues.
Mixed race black and white couples face higher odds of prematurity and low birth weight, which appear to contribute to the substantially higher demonstrated risk for stillbirth. There are likely additional unmeasured factors that influence birth outcomes for mixed race couples.
Mixed race offspring are too genetically dissimilar to either parent for them to donate bone marrow if the child needed it.
Anecdotally, I know a hispanic-chinese couple who had an extremely difficult pregnancy that required bedrest and the woman almost died in childbirth. Another couple is both the same european ancestry and the mom climbed mountains and went running during pregnancy and did a natural birth with no painkillers. Coincidence?
Heck, women used to work up until labor.
