I’m trying to estimate narrow sense heritability (h2) of some traits using offspring-parent regression. For general traits, we have to plot mid-parent values against average offspring values and then estimate h2 from the slope of the regression line.
I wonder how to estimate h2 if those interesting traits are secondary sexual traits, for example horn of rhinoceros beetles which is presented only in males. I cannot use mid-parent values because females lack horn. Can I estimate h2 from the slope by plotting between father values against average son values directly?
Thank you
Dear Nut
Yes, you can use regression of the offspring mean on Sire, in this case, the slope estimation ( b ) will represent half the heritability estimation ( h2 = 2b ).
Good Luck
yes, you can use the regression of the offspring on sire, so the slope estimation(b) will represent half the heritability, then this value should be multiplied by 2 which will be the heritabilty
