I have an inquiry regarding the exact function of height genes.
To my knowledge, although they are heavily regulated by epigenetic factors, height genes can have either an "on" or an "off" allele, and the probability of the person being "tall" shows positive correlation with the number of "on" height genes alleles he has.
However, I could not find any resources showing the exact function or mechanism of these genes' function. Do these genes code for a specific protein when they are "on"? And if there are any, how do these proteins increase the probability of the person being "tall"?
