Changes in stats and colors of bred offspring
Released v252.0

Mutations are a breeding-mechanic that can randomly alter the stats and color of a Dino's offspring. For further insights see the External links-section.

Probability of Mutation[edit | edit source]

For each offspring there are three possible stat-mutations which can happen at the same time. Each one of the three possible mutation has a chance of 2.5% to happen.

The probability for at least one mutation in an offspring is 7.3140625%, for at least two mutations is 0.184375% and for three mutations 0.0015625%.[1]

Exceptions[edit | edit source]

The following dinos are exceptions from the list due to their ancestry only from Wild Ancestors upon birth:

Added with the fact they can't be bred means they can never get mutation.

Mutation Mechanics[edit | edit source]

Mutation selection[edit | edit source]

When two Dinos breed, the offspring can have

  • No mutations, selecting stats from the parents as normal, or
  • A mutation does occur, meaning:
    • A random stat change, adding two wild levels to a random stat(not always visible because wild creatures don´t gain Movement Speed)
    • A random color change (not always visible because some creatures don´t use all color regions)

Stat selection[edit | edit source]

When an egg hatches, its stats are randomly selected from either parent, with a 55% chance to get the better of the two. Regardless of this though, a mutation from one parent can still affect a stat taken from the other. This means a Fully Mutated Dino (≥20/20 on both sides of inheritance) with higher stats bred with a Non-Fully Mutated Dino (≤19/20 on the respective gender's lineage) can still receive mutations on the stats from the Fully Mutated Parent, allowing you to further increase breeding potential. This is because the stats are chosen first, and then the mutations (if any are to occur), are selected and applied.

When a mutation does occur, a random level-able stat is chosen, and has two wild levels applied to it (a flat increase, compared to a Tamed Dino's percentage based increase). This means there is a chance that a mutation will occur, but be effectively lost due to the fact that levels placed into movement speed on a wild dino do not actually increase the movement speed.

Mutation counter[edit | edit source]

The Mutation counter is the number shown on your ancestry tree. This is represented by a 0/20 score at base and increases with concurrent breeding.

A +1 on the patrilineal/matrilineal side of the mutation counter is based on which parent the mutation "came" from, but for the purpose of advanced breeding it’s not too important.

The only important thing is that new mutations will not occur if the Parent Dino has 20+/20 inheritance from their respective gender's lineage.

This means that in order to breed new mutations, a Male Dino would need ≤19/20 mutations on only the patrilineal side, while a Female Dino would need ≤19/20 mutations on only the matrilineal side. (For example, a Male Dino with 12/20 patrilineal mutations and 20/20 matrilineal mutations would still be viable for breeding)

The counter on mutation inheritance works on its own accord, and does not actually show the actual number of mutations on a Dino. What the counter does do is take the sum of mutations of BOTH inheritances, adding them together and then placing them on the respective inheritance of the Parent Dino.

An example being:

Matrilineal mutations/20 Patrilineal Mutations/20 Number of New Mutations
Female Parent 1 4 N/A
Male Parent 10 5 N/A
Baby 1 5 15 0 (No additional levels)
Baby 2 5 16 1 (+2 levels to a random stat)
Baby 3 6 15 1 (+2 levels to a random stat)
Baby 4 6 16 2 (+4 levels to a random stat)

Color[edit | edit source]

When a mutation occurs, a color mutation will always occur as well. However, it may not be immediately apparent. First, a color will be randomly selected from all available colors, usually from IDs 1 - 18. This color is then randomly applied to one out of six color regions on a creature. Most Dinos only use four color regions, which means an unused region may be selected, effectively losing the color aspect of the mutation. Another reason for not seeing a color mutation could be that the mutated color is the exact same or very similar to the unmutated color. Once a color is mutated, it is passed on to the next generation like any other color would be (50% chance between which parent the region will take its color).

How to Breed Super Dinos[edit | edit source]

Selective mutation breeding / mutation stacking

1)      Breed a dinosaur that has the best stats that you can find. – the dinosaur has to have 0-19/20 mutation in his respective category, e.g. male 0-19/20 mutations on patrilineal side, female 0-19/20 mutations on matrilineal side,

2)      Get a level 1 dinosaur and breed the 0 points in movement speed to the baby. Every “wild” point in movement speed is a lost point so you don’t need them and can substitute them for points in another stat. Remember we are going for the level cap (level 450) so every level is important (e.g. getting 60 levels in oxygen on a dinosaur for boss fights is not very useful).

3)      Get a breeding pair 1 male and as many females as you can (the more the faster the whole process gets). – the dinos has to have 0-19/20 mutation in his respective category, e.g. male 0-19/20 mutations on patrilineal side, female 0-19/20 mutations on matrilineal side,

4)      Breed…a lot.

5)      A) Get a mutation in the stat you are looking for (e.g. HP)

         B) Get a mutation in the stat you are looking for (e.g. HP) on a baby that got the higher stat from parents.

6)      Breed your new mutation to a MALE dino.

7)      Swap your original male with the new mutated (e.g. HP) male dino.

8)      Repeat point 5B-7.

9)      Stop if your dino reaches lvl 378 – dino lvl cap is lvl 450 (included), 449-71=378, any dino that gets to lvl 450 (included) will be deleted by the game (official servers), you get more stats if you add levels manually because you get a % on the lvl up of tamed dinos rather the a flat value like in a mutation (99% sure)

10)   Stop if you reach 184 lvl in specific stat. – stat values are capped at 255 levels, 255-71=184, after that the stat resets - you get more stats if you add the level manually because you get a % on the level up of tamed dinos rather the a flat value like in a mutation (99% sure)

For this process it’s not important that after some time your male will have more then 20/20 mutations. As long as yours female has 0-19/20 on the matrilineal side you can always get a mutation. The female dino provides a possible mutation and the male dino better stats.

Remember if both dinos have 20+/20 mutation in their respective side (male on patrilineal and female on matrilineal side) you can’t get a new mutation. So it’s pointless to try get a new mutation this way.


I was going to breed a god rex.

1)      Starting rex stats breed from all best rexes I had at the time.

Starting stats

2)      Getting a lvl 1 rex. (Tamed lvl 1 rex, very low taming efficiency)

3)      Breeding a rex that has no lost points in movement speed

4)      Selective mutations breeding – for a very long time

I was breeding for hp and melee so I took every hp or melee mutation.

5)      Final stats

6)      Breeding for color – such op dino needs to look nice too

I was keeping every new color mutation that I got in the process, so I ended up having like 200+ rexes of every color imaginable on every region.

Yes, the rex in the example was bred a little different, I got rid of all the levels in movement speed in the end.

FAQ[edit | edit source]

  • A creature got +2 levels in a stat, but the colors seem to be the same without color-mutation.
All creatures have 6 color regions, but not all species use all 6 of them. A color-mutation can happen in all 6 of them. If a color-mutation happened in a color region that is not used/visible on a creature, it can seem as if the creature didn't receive a color-mutation.
Another reason for not seeing a color mutation could be that the mutated color is the same or very similar to the unmutated color.
  • A color seems to be mutated, but no stat-values changed.
The stat mutation is in a stat that don't increase the value with wild levels, e.g. movement speed. A wild stat-increase is always seen in a higher torpor value and higher total level, though.
  • The total level increased with no stat increase and no color change.
This can happen as a combination of the first two cases. The only thing that visibly changed is the torpor-value and the total level.
  • Can the mutated color be the same as the original color?
Yes, the mutation color is chosen randomly.
  • Can a creature mutate twice at the same time?
Yes, up to three mutations can happen for an offspring, with two stat-levels and one color-change for each mutation.
  • Can creatures be bred infinitely to increase their stats?
No, there is a level cap of 450 on official servers, any dino that reaches level 450 is deleted by the game (official servers). Note that selective mutation breeding is a very long process and it’s going to take months of real time, until that limit is hit.
  • Could a low level creature with 3 mutation in a stat used to transfer these mutations on a high level creature to increase its stat-values?
No, mutations are bound to the stat they influenced.
  • Can the offspring of parents with p20+/20 m20+/20 have mutations?
No, at least one parent with a mutation counter of less than 20 on its respected side is needed to have an offspring with a mutation.
  • Can the offspring of a parent with more than 20 have mutations inherit a stat of this parent and have a mutation on this stat?
Yes, if the other parent has a mutation counter of less than 20.[2] This method is used in selective mutation breeding.
  • Does a high mutation counter imply a good creature?
The mutation counter doesn't reflect the stats of the creature and is independent of them, so a creature with 0 mutations can have very high levels and a creature with a high mutation-counter can have 0 levels in each stat. For more information watch one of tagbacktv’s videos on mutations.
