Females take several years to get to breeding size. In that amount of time, your investment in that female depreciates possibly many times over. A multiple gene male may cost a tad more initially, but your return is quicker. A male can be ready to breed in as little as 4-6 months if he is a good eater and interested in the ladies. I had Bananas breeding at 4 months old and 450g last season. Pair that with the fact that your male can handle breeding 4/5/6 females depending on his health during breeding season.
Say you want to make BumbleBees..... would you buy 0.3 Bumblebees and a 1.0 Normal male? That would be crazy. You spend ~$200 per female as babies, they take 2-3 years to get to breeding size and they will depreciate in that time.
The wiser choice is to get a 1.0 BumbleBee and breed him to 3-4 Normal females. The odds are the same, your investment is much less, your turnaround is quicker, etc...
I've posted this great article probably 50 times.
Great info- even for the experienced breeder (just to keep you on track).
