For example , genotypes that differ at the alcohol dehydrogenase locus in
Drosophila differ in their tolerance to ethanol , giving rise to variance in viability .
As larvae , these genotypes also differ in their tendency to avoid ethanol (

Nevertheless , some estimates of variance components ( Table II ) show an
interesting regularity in that the proportion of the genetic variance that is
nonadditive ( Vp + Vi ) is relatively greater in traits such as egg production that
ought to be ...

VARIATION We are also interested in the variation represented by a series of
measurements . The most useful measure of variation is the VARIANCE , defined
as the mean value of the square of an observation ' s deviation from the
arithmetic ...
