What's wrong with sibs?

[DennisM]

Thanks Dennis- I'm still trying to understand the whole sib thing. So if you pair a Jungle Jag with a pure Jungle the normals would be JJ sibs? And if the sib was later paired with another pure jungle they would only produce normals, and maybe coastals, but no jags? The sib should also not be paired with another jag. Am I getting this partially correct?

there's no reason not to pair a normal (sibs are normals) with a jag. The issue is with jag to jag, the homozygous jag (super jag) is lethal. an expected 25% of jag to jag offspring would have the lethal homozygous outcome.
