Can someone explain to me the differences

I was looking forward in getting a Jaguar carpet this Springand my friend was telling me he knows somone who will have 88%IJ jags and 75% Coastal Jags. So my question is how do you get the % of the mix which ones will be the more brighter(yellower) and also if anyone has any pictures of these.
Thanks Mark

You get the percentage of mix based on how many sequential breedings to a specific type you have.

So, for the 88% IJ you start with a Jag and breed to a IJ. All those offspring are 50% IJ
Breed a 50% IJ Jag to an IJ and all those offspring will be 75% IJ
Breed a 75% IJ Jag to an IJ and all those offspring will be 88% IJ

As for which will be most yellow... I can not say for certain. Lots of people argue that the IJ Jags are more yellow but I have seen some screamers that were not IJ
