Okay, so I am logging my success ratio for trying to turn my pets mutant through dna minipet breeding- so far today I have tried the following pairings with the following success:

1: Orange Jessup; blue Knutt; green DNA-
"successful operation, green jessutt"
No mutation.

2: Blue Knutt; orange Jessup; blue DNA-
"successful operation, blue jessutt"
No mutation.

I will keep you updated as I try more combinations (I want mutant Jessups, Kaalas, Knutts, Speiros and Troits)

PS, making DNA minipets for you if you provide the DNA
