In quantifying the proportion of phenotypic variation that is due to differences

Question

In quantifying the proportion of phenotypic variation that is due to differences in genes, narrow-sense heritability quantifies ___________ genetic variation, while broad-sense heritability also accounts for ______________ genetic variation.

I know narrow sense heritability is Va/Vp which is also equal to Va/Va + Vd + Ve

Also, i know broad sense heritability is Vg/Vp which is also equal to Vg/Vg+Ve

Vg:genetic variation

Vp: phenotypic variation

Ve:envitionmental variation

Va: addative genetic variation

Vd:dominance genetic vatiation

Also I know Vg=Va+Vd

I think the first blank is addative genetic vatiation... THANKS

Explanation / Answer

Yes the first blank is additive genetic variation.

Narrow sense heritability is always less than the broad sense heritability and denoted by “h2”.

In quantifying the proportion of phenotypic variation that is due to differences in genes, narrow-sense heritability quantifies _the additive __ genetic variation, while broad-sense heritability also accounts for _ total phenotypic variance____ genetic variation.
