Unformatted text preview: can do this by rearing everyone in the same environment, e.g. greenhouse. •  Now in prac-ce this is nearly impossible, even in a controlled environment like a greenhouse can not get environmental uniformity. •  Instead can raise cloned or highly inbred individuals so VG = 0 in as -ghtly controlled environment as possible and measure VP. •  This would allow us to determine VE •  We could then raise a bunch of gene-cally variable individuals in the same environment as before (so can use VE). •  Could then obtain the gene-c variance of the variable individuals by subtrac-on. VG (gene-cally variable individuals) = VP (gene-cally variable individuals) – VE of gene-cally iden-cal individuals). •  Can then es-mate broad- sense heritability...
