text: Yo, check it out, here's the scoop,
  Sex ratios in O. aureus, they're mad complex, ooh!
  From 62 matings, single-pair, no doubt,
  Males were in deficit, only 41.4% about.
  
  Peaks in the ratio, they were all over the place,
  1 to 1, 3 to 5, and 1 to 3, embrace!
  Hybridizing with O. mossambicus and O. spilums too,
  O. niloticus as well, sex ratios went askew.
  
  Hybrid data be showin' complexity,
  Determinin' sex, it's a mystery.
  Can't make solid inferences, it's a tough task,
  Intraspecific sex determination, can't be unmasked.
  
  Progeny testing of sex-reversed males, listen,
  Ratio 1 to 3, females winnin' the competition.
  Sex-reversed females, it's a lonely road,
  Ratio 1 to 0, no males in the abode.
  
  Aberrant ratios suggest Mendelian inheritance,
  Autosomal recessive gene, that's the appearance.
  Epistatic to the major sex-determining gene,
  W and Z, they be playin' the scene.
  
  Triploids and gynogens, they support the claim,
  Recombination between centromere and the sex-determinin' game.
  Progeny testin' of a female mitogyne, it's wild,
  WW "superfemale," only givin' birth to child.
  
  But hold up, it ain't just a two-factor show,
  Sex determination in O. aureus, gotta know,
  Rare factors, autosomal or environmental, they sway,
  Exceptional ratios, they come into play.
  
  So, in conclusion, O. aureus, it's a real mystery,
  Multifactorial mechanism, sex determination history.
  With female heterogamety as the primary deal,
  That's the underlying mechanism, gotta keep it real.
