The other big reason you haven't seen more BEL's from Mojave to Mojave, is that Mojaves are cheap now, but 2 years ago, Mojaves were still about $2,500 and 3 years ago, they were still abou $5,000. Which means that to be producing BEL's, you would have had to have bought a female at minimum 2 years (to make them this year). There just aren't alot of people out there with breedable female Mojaves.

It seems to me that alot of people forget about how long it takes to raise a female (which is paramount in making supers). It's easy to crank out the Heterozygous from of a co-dominant triat animal, but getting the Homozygous form takes a female, and typically 3 years of work.

I hope that helps explain why BEL's aren't cheap yet.
