text: Yo, listen up, let me tell you 'bout microsatellites
  Polymorphic genes, they're really quite a sight
  Used for population genetics, they're real cool
  But when it comes to stingless bees, they act like a fool
  
  Low levels of polymorphism, what's the deal?
  Turns out the primers used weren't specifically real
  Not designed for these species, that's the cause
  So we compared some primers, let me give you the pause
  
  Melipona rufiventris and M. mondury, we gave it a shot
  Used specific and heterologous primers, that's what we got
  Specific primers showed more polymorphic loci and alleles
  And an increase in observed heterozygosity, that really sails
  
  So remember, if you wanna study a population right
  Use species-specific microsatellite primers, that's the highlight
