Female CG (or Banana) will produce equal sex ratio, the males produced by those females are female makers, this means the CG offsprings sired by that male will be females while the rest of the non CG offsprings will be males.

A male CG that is produced by a Male CG is a Male maker, producing Male CG hatchlings while the non CG hatchlings will be females.

Of course it's not always true and a male maker can produce females every non and than and vice versa.
