While we do not necessarily ascribe to a central dogma, the evolution of the Chromotones is in other ways a genetic story.
For more than a decade, 23andMe had no a cappella group. Maybe we were too busy getting our code-on. Then in 2018 the nucleotides turned; a founder population realized we shared a karyo-ketype and created the Chromotones. Our success in a company variety show naturally selected us to recombine and our happy-lo group of neanderthal cousins now features dominant percussive traits and SATB polymorphism -- including a strong bass pair.
With a majority of our gene pool being new to a cappella and performing, our rough edges are part of our charm. And although we're not all genetically predisposed to match musical pitch, our phenotypes are proof that DNA ain't destiny.
