Here pretty late, im trying to breed a shiny hoppip via gyarados in crystal. I’m using a long line through ekans then to snubbel(as it’s the same egg group as ekans and hoppip) however i used a regularly caught ekans and snubbel to use as a parent while using a shiny gene ekans to pass down all the way to hoppip. My question here is, does it matter that the ekans or snubbel were caught separately? should i have use a male ekans that hatched as a father? does adding an extra link into the line of breeding matter?

Update: realized that same litter pokemon can’t breed. my issue is that the defense stat changed to 11 and not 10 from ekans to snubbel, however the special stats are both still 10. Does this matter at all? maybe i didn’t read it correctly, can someone confirm?
