Are there any genetically informed studies of the effects of Asian parenting?  Google Scholar has zero hits for the union of “Asian parenting” and “shared environment.”  And in all my years of reading this literature, I can’t recall a single twin or adoption study of any behavioral trait conducted in an Asian country. 

Bruce Sacerdote’s famous Korean adoption study doesn’t count, of course, because it studies the effect of American parenting on Asians.

American and Australian twin and adoption studies no doubt contain some Asian parents, but total number of families with Asian parents must be very small.  Even now, Asians are under 5% of the U.S. population, and under 10% of the Australian population.
