Of genetic striping,is a recessive trait.(As far as I know,I have never bred them.),I'm not sure what percentage of striping is required,or,considered significant,in visually distinguishing a homozygous from a het that may show some connectivity by chance,since most homos are not fully striped.I would think that if this occured frequently,one would need specific,accurate information on the genetic status of the adults that were bred to produce the animals in question...all geneticlly transmitted mutations,that I can think of,produce heterozygotes,or,intermediate forms when bred. that includes dominant/co-dominant/and,recessive traits...in dominant traits,the hets & homos look similar,but,both obviously differ from "normal"...in co-dominant traits,there is visual distinction between hets & homos,but both look different from "normals"...in a recessive trait,the characteristics are not seen,or,visibly expressed in heterozygous form,only the homozygotes express the characteristics...this is by definition,what qualifies it as simple recessive. the definitive characterstic of various dominant traits is,that the hets express some visual cue that makes them distinctive from "normal",or,"wild types"...it is expressed in the first generation rather than only the second.hope this helps
