text: Yo, we analyzed the pedigree segregation,
  Checkin' out one- and two-locus situations,
  Inheritin' phenylthiocarbamide (PTC) taste deficiency,
  Upgradin' the one-locus recessive with efficiency.
  
  We added another allele or a whole new locus,
  Predictin' two types of nontasters, focus,
  Nontaster by nontaster matin' bringin' taster offspring,
  Our data and past studies in harmony they sing.
  
  We used the Harris and Kalmus dilution method,
  Fit our data set, fam, the results were legit,
  1,152 individuals from 120 families strong,
  Two-locus model triumphed, proved the others wrong.
  
  One locus controls PTC tasting, that's the first,
  While the second controls taste, it's not the worst,
  Physiology of PTC tasting backs this claim,
  Genetic linkage studies puttin' it in the same lane.
  
  But yo, we need more study to be precise,
  Evaluate the model, make sure it's right on ice.
