(C) The formula for the number of different genotypes produced by a self-cross of an organism with $n$ heterozygous gene pairs is $3^n$.In the given genotype $AaBbCcDdEeFfGg$,we count the number of heterozygous pairs $(n)$:$Aa$ $(1)$,$Bb$ $(2)$,$Cc$ $(3)$,$Dd$ $(4)$,$Ee$ $(5)$,$Ff$ $(6)$,$Gg$ $(7)$.Thus,$n = 7$.The number of different genotypes is $3^n = 3^7$.
