Clearly many differences between genotypes may contribute to differences in
fitness . A difference in any value of 1x up to the age of last reproduction may
constitute a difference in fitness ; but after reproduction ceases , the individuals
do not ...

The phenotype in question could be a morphological or physiological trait , or a
component of fitness , or fitness itself . Lewontin and Kojima ( 1960 ) analyzed the
case in which the genotypes have these fitnesses : BB BB ' B ' B ' AA a C a AA ...

If the population is at allele frequency equilibrium , mean fitness is not increasing
, so the additive genetic variance in fitness itself must be zero , and the stronger
the correlation between a trait and fitness , the closer to zero VA will be for that ...
