      There's this discussion going around in science circles about the question of, separate from ethics, eugenics would "work" in the sense of selecting for traits. I don't wanna even dip a pinky in this on twitter, but I do have a technical question:

      I see lots of claims saying that a trait can't be selected for if it's highly polygenic. I see why this might make it harder to select for and more likely to produce undesired knock-on effects, but I don't see why it'd pose a serious problem.

      Like, presumably lots of qualities of highly domesticated animals (hair length, tallness, docility) are polygenic, but it seems possible to select for them just fine. What am I missing?

      In dogs some huge percentage of the variation in height is due to variations in a single gene, an artefact of artificial selection, no doubt.

      In humans, there are dozens of genes involved in height.

      Which is why China's effort at breeding Yao Ming by encouraging his exceptionally tall mother and father to get together didn't work.

          Wrong conclusion. Of course (with some regression to the mean) tall people are more likely to have tall kids. No one is questioning banal observations about hereditary.

          Heredity works but it's probabilistic so it doesn't work when you add more examples - this is due to the central limit theorem /sarc
