well in a breeders collections say he has 100 females. he only needs 20 males for those females to have a decent ratio. so females will be in more of a demand. once the banana becomes not as rare. there will be a point where females will be worth more than males.
with your lesser theory. when it take 3 years on average to get a female to breeding size. no one is going to waste a morph female with a normal male. I have a female visual pied and I wouldn't waste it to a male pied. in the ball python breeding hobby. to get a female up to breeding size is a huge chunk of time and many things will change greatly.
