text: Yo, check it out, let me break it down
  Human B lymphocytes, they run the town
  They got five flavors, specificities they claim
  Defined by 32 antisera, that's their game
  
  The antisera, they did their thing
  Absorbed those platelets, removed HLA swing
  Out of 400 tested sera, only the chosen few
  Defined those specificities, now we're getting through
  
  Them five flavors, they stick together tight
  High correlation coefficients, shining bright
  From 0.6 to 0.9, that's the range they roll
  In the Hardy-Weinberg equilibrium, they control
  
  These specificities, they got a genetic spot
  Alleles at one locus, that's the plot
  No association with HLA, that's a fact
  They do their own thing, that's how they react
