Viability help!!!

[General_Mueller]

Can someone please explain wtf the viability stat in the genome process is??? Thanks ahead of time..

The chance you can successfully hatch the dinosaur in the incubation process.

[Sorcerer Mickey]

Viability is how likely you are to succeed in incubation. The higher it is, the more likely the dinosaur will hatch

[kasakuie]

Viability is the percent chance of said dino incubating successfully when creating it in the Hammond Lab building. The better your dna percentage is the higher the Viability stat is. It starts to drop when you start adding in genome mutations but there are upgrades to the Lab that gives bonus success chance percentage.

Thanks for the help...

Sorry for the Necro, but...

I just researched Success Rating 4.0. I outfitted a Hammond Lab Creation Lab with three of these upgrades to get a bonus of 120%.

This means: I could manipulate the genome of a Dinosaur to -20% viability and still have exactly 100% chance for the embryo to hatch, right?

But if that's right... I could work around the Deinonychus genome to bring it to -139% viability. Even with my bonus of 120% it still has -19% chance to hatch... this would be a zero chance, no matter how often I try. Right again?

That is correct x2, yes.
Having 3 SR4 upgrades, you'd still have to have at least -119% to even get 1% of them hatching. Anything lower automatically makes the hatching fail, even if it doesn't fail the instant you start it.

I'm assuming this was implemented this way so you don't actually have a legitimate way to get the best possible rating of a Dino... well, without using Combat Infamy anyway

Ok, thanks alot Arretrea.

I thought it was that way, but the -139% made me wonder.

Guys I dunno how to tell you this but I regularly make dinos with negative viability (although they do fail often). So it turns out what viability means isn't a strict translatable percentage to hatch failing, at least it isn't 1 to 1 (Oh my beautiful spinosaurus literally just hatched with -47% viability, nice)
Edit: Seems viability upgrades aren't added to the viability stat. Add the two together for the success chance (in my case -47% + 60% = 13% success chance)

[Athos42]

If you have three Success Rate 4.0 upgrades, your Spino will hatch with -47 + 120 = 73 percent chance. Not that bad, three out of four tries.

You need 2 Success Rate 2 upgrades of 20% each and and one Success Rate 1 of 10% to have at least a chance for it to hatch at all. You need to add up to 1% or higher. With these, your Spino would hatch with a 3 % chance.
