Convenient Gender Shift

Chakats never run into situations where both are in male or female phase. It's always something compatible. Chakat A goes into male heat, and immediately Chakat B goes into female heat. At the exact same time. I've never read a Chakat story where A and B go into male heat at the same time, or what happens as a result of that. The author just assumes that man's genetic creations will just naturally turn out perfect as the original models (which also don't always turn out conditions ideal for reproduction).
