Why are females so much more desirable than males?

[missi182]

low end morph---females more expensive
high end morph---males more expensive

this strategy is used to keep prices high

That doesn't make sense. Any high-end/new morph is going to cost more regardless of if it is male or female, and female will always cost more than male regardless of which morph it is.

i.e - albino female costs more than albino male
- normal female costs more than normal male

...same thing, different price range
