      Can’t stop thinking about how there is no sex difference in polygenic scores for height

      I mean, given that PGS are based on autosomes, it's pretty obvious that there can't be gender differences in any PGS.

      Well, not for long since it resets every generation, but one could have them by stark differential mortality based on PGS. (if one Sparta style killed all the newborn boys with PGS below 50th centile)

      Sex dimorphism doesn't require sex chromosomes. Autosomal SNPs (with equal freqs by sex) can produce dimorphism via sex specific effects (usually due to gene expression interacting with hormones). Quite a few papers on this

      We are discussing polygenic scores specifically.

      They usually define these without option for interactions and using autosomes only so the betas can't differ by sex.

          Also, dimorphism isn't necessarily due to sex chromosomes, in some species:https://doi.org/10.1111/jeb.12596 …

          Isn't that just a convention though? I have seen papers dealing with sex specific effects of autosomal SNPs.
