An octive is literally twice the frequency of the notes below it, how is that genetic? The only thing that unique in music is that a 3/2 ratio (a perfect fifth) only makes sense in 5, 7, and 12 note scales and even then it’s slightly out of tune by a couple of cents so you can either use relative temperment or even temperment depending on preference. Alternatively you can optimize for other ratios and get all microtonal.
