If by "general intelligence" we mean "performance in resolving IQ test", I
think that too many phenotypic traits are involved for it to be plausible
that the results be determined by just one or a very few genes, as it
appears to be the case for the "absolute ear" in music.

As you say, however, this does not change much as to the role of one's
genetic profile in achieving the results concerned.
