Breeding / Compare Mates question

[sagefox]

So i'm trying to raise up an animal thats 100% in all 4 areas. But theres something I don't understand. When you do the 'compare mates' option it shows you some grey and red bars. What do these mean?
I'm assuming the grey bar is the potential outcome, but whats the red bar mean. Is that the upper cap?
I have two unrelated animals both with very high stats, 100% in 3 areas and 90% in the other, but when i try breed them it shows the fertility and immunity bars are being almost entirely red, why is that when theres no incest involved, and they are otherwise very healthy?

For some reason fertility and immunity work best when a high stat animal is bred with a low stat animal. Find a peafowl with lower fertility and immunity and see if the offspring outcome will be better.

For some reason they decided to make it so that if you breed animals with matching fertility and immunity you get horrible results. Hence your image.

Kinda makes sense for immunity, but I can't understand why breeding 2 high fertility animals together would net a bad result.

Edit: afaik the red bar shows the potential outcome values, grey bar is just the background.

Yes, red is the potential outcome.

The two animals are probably distantly related (or have just randomly the same gene for fertility and immunity). If two animals with the exact same kind of genes get combined, the possible outcome will get lower.

Don't mistake "same genes" here as the same "number". You can (and should) combine animals with hight stats to get better outcomes.

164 peafowls later I finally got it

I don't understand how my two red pandas had a 0% chance for offspring, and then had offspring. Fertility was good too. Seems like a bug.

From what i've worked out even with a 0 fertility rating you can still breed, as long you have some basic research into the animal. If you fully research an animal it gives you a 30% breeding boost, so an animal with 0 fertility can still have a 30% chance to breed.
The 'red' bars when you do compare mates are actually the predicted stats. So if a bar is entirely red like fertility or immunity usually is, that means the baby will randomly get a score any where from 0 - 100.
Essentially what you need to be doing is breeding for size/longevity only, as those are the two stats that will progressivly get better with each generation, where as immunity/fertility are almost essentially random and arent worth worrying about too much.
