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 ...

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

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 mean of the population or sample : ( X – ) + ( X2 – 7 ) + .
