If the equivalence principle holds , what does gravity influence ?
He begins with a population of genotypes consisting of pure dominants ( AA ) , heterozygotes ( Aa ) , and pure recessives ( aa ) in the relative proportions p:2q:r with the conditions noted above , that is , Rewriting this as ( " p " + " q " ) + ( " q " + " r " ) = 1 and squaring both sides yields Hardy ’s result : formula_30 Hardy ’s equivalence condition is formula_31 for generations after the first .
